**Project name:** Enhanced Media Experience with AI-Powered Commercial Detection and Replacement
Description
============
I propose developing **GStreamer Plugins** capable of processing video inputs based on their classification.
The plugins will identify commercials and either replace them with alternative content or obscure them,
while also substituting the audio with predefined streams. This enhancement aims to improve the media
consumption experience by eliminating unnecessary interruptions. I intend to **explore various video
classification models** to achieve accurate detection and utilize TensorFlow Lite to leverage the **native
accelerators of BeagleBone AI-64** for high-performance, real-time inferencing with minimal latency.
I believe real-time high-performance would be the most critical thing for this project and I intend on testing
a few different ways to see which one works best.
Goals and Objectives
=====================
The goal of this project is to detect and replace commercials in video streams on BeagleBoard hardware
using a GStreamer pipeline which includes a model that accurately detects commercials with minimal latency.
Comparison of different model accuracy can be done by doing some manual analysis and trying different video
classification models and to finally use the best performing option to be included in the GStreamer pipeline
for inferencing of real-time videos. This would be the result presented at the end of the project timeline.
For phase 1 evaluation, the goal is to build a training dataset, preprocess it and fine-tune and train a Video
Classification model. For phase 2 evaluation, the goal is to use the the best model identified in phase 1 for
commercial detection and build a GStreamer pipeline and use native accelerators present in BeagleBone AI-64
for high-performance.
In order to accomplish this project the following objectives need to be met.
1. Phase 1:-
- Develop a dataset of videos and corresponding labels indicating the presence of commercials in specific segments.
- Preprocess the dataset to ensure it's suitable for input into deep learning models. Moreover divide the datset into train, validation and test set.
- Apply transfer learning and Fine-tune various deep learning models and train them on the prepared dataset to identify the most accurate one for commercial detection in videos.
- Save all trained models to local disk and perform real-time inference using OpenCV to determine the model that yields the best results with high-performance.
2. Phase 2:-
- Based on all the options tried in Phase 1, decide on the final model to be used in the GStreamer pipeline.
- Compiling the model and generating artifacts so that we can use it in TFLite Runtime.
- Building a GStreamer pipeline that would take real-time input of media and would identify the commercial segments in it.
- If the commercial segment is identified the GStreamer pipeline would either replace them with alternative content or obscure them, while also substituting the audio with predefined streams.
- I will also try to cut the commercial out completely and splice the ends.
- Enhancing the Real-time performance using native hardware Accelerators present in BeagleBone AI-64.
**Methods**
***********************
In this section, I will individually specify the training dataset, model, GStreamer Pipeline etc. methods that I plan on using in greater details.
Building training Dataset and Preprocessing
============================================
To train the model effectively, we need a dataset with accurate labels. Since a suitable commercial video
dataset isn't readily available, I'll create one. This dataset will consist of two classes: commercial and
non-commercial. By dividing the dataset into Commercial and Non-Commercial segments, I am focusing more on
"Content Categorization". Separating the dataset into commercials and non-commercials allows our model to
learn distinct features associated with each category. For commercials, this might include fast-paced editing,
product logos, specific jingles, or other visual/audio cues. Non-commercial segments may include slower-paced
scenes, dialogue, or narrative content.
To build this dataset, I'll refer to the **Youtube-8M dataset** [1],
which includes videos categorized as TV advertisements. However, since the Youtube-8M dataset provides encoded
feature vectors instead of the actual videos, direct usage would result in significant latency. Therefore,
I'll use it as a reference and download the videos labeled by it as advertisements to build our dataset.
I will use web scraper to automate this process by extracting URLs of the commercial videos. For the
non-commercial part, I will download random videos from other categories of Youtube-8M dataset.
After the dataset is ready I will preprocess it to ensure it's suitable for input into deep learning models.
Moreover I'll divide the datset into train, validation and test set. To address temporal dependencies during
training, I intend to employ random shuffling of the dataset using
```tf.keras.preprocessing.image_dataset_from_directory() with shuffle=True```. This approach ensures that
videos from different folders are presented to the model randomly, allowing it to learn scene change detection
effectively.
Video Classification models
============================
**MoViNets** is a good model for our task as it can operate on streaming videos for online inference. The main reason behind trying out MoViNets first is becaue it does quick and continuous analysis of incoming video streams. MoViNet utilizes NAS(Neural Architecture Search) to balance accuracy and efficiency, incorporates stream buffers for constant memory usage [Fig. 1], and improves accuracy via temporal ensembles [2]. The MoViNet architecture uses 3D convolutions that are "causal". Causal convolution ensures that the output at time t is computed using only inputs up to time t [2][Fig. 2]. This allows for efficient streaming.
This make MoViNets a perfect choice for our case.
Since we don't have a big dataset, we will use the pre-trained MoViNets model as a feature extractor
and fine-tune it on our dataset. I will remove the classification layers of MoViNets and use its
pre-trained weights to extract features from our dataset. Then, train a smaller classifier (e.g., a few fully connected layers) on top of these features.
This way we can use the features learned by MoViNets on the larger dataset with minimal risk of overfitting.
This can help improve the model's performance even with limited data.

:alt: Standard Convolution Vs Causal Convolution
.. centered::
If MoViNet does not perform well than we can use other models like **Conv+LSTMs** [Fig. 3][3]. Since a video is just a series of frames, a naive video classification method would be pass each frame from a video file through a CNN, classify each frame individually and independently of each other, choose the label with the largest corresponding probability, label the frame, and assign the most assigned image label to the video.
To solve the problem of "prediction flickering", where the label for the video changes rapidly when scenes get labeled differently. I will use **rolling prediction averaging** to reduce “flickering” in results. And I will maintain a queue to store the last few frames and whenever a scene change is detected, all frames in the queue would be marked with the current result, allowing for retroactive scene modification.
The depth of the queue will be determined through experimentation to find the optimal setting.
The Conv+LSTMs model will perform well as it considers both the spatial and temporal features of videos just like a Conv3D model. The only reason it is not my first choice is because MoViNets are considered to be better for real-time performance.
.. image:: Assets/Figure3.png
:alt: Conv3D+LSTMs
.. centered::
- **ViViT**: A Video Vision Transformer, this is a pure Transformer based model which extracts spatio-temporal tokens from the input video, which are then encoded by a series of transformer layers [4]. I have kept this as an optional method because our problem is of binary classification(either Commercial or Non-Commercial), so using such a complex model for this small problem may not be as efficient as other models.
- **Audio fingerprinting**: This method involves extracting unique characteristics or features from audio signals to create a compact representation, often called a fingerprint. These fingerprints can then be compared against a database or used for various audio processing tasks [5]. I have kept it as an optional method because it may sometimes yield poorer results compared to deep learning models like MoViNets and Conv+LSTMs, particularly in tasks requiring complex audio understanding.
- **Scene Change Detection**: This approach involve detecting scene changes to segment the video into distinct segments or shots based on difference between pixel values of two consecutive frames etc [6]. And then applying video classification model on segmented frames. I have kept this as an optional appraoch because I think adding an additional step would cause unnecessary challenges.

I will choose the best performing model based on model's performance on:-
1. **Evaluation metrics**
- Accuracy: This metric provides a general overview of how well our model is performing overall. It's a good starting point for evaluating performance, but it might not be sufficient on its own, especially if the classes are imbalanced.
- Precision and Recall: These metrics provide insights into the model's ability to minimize false positives (precision) and false negatives (recall). Since our problem involves binary classification, precision and recall are essential for understanding the model's performance on each class (commercial and non-commercial).
- F1 Score: It provides a balanced measure of the model's performance. A high F1 score indicates that the model effectively balances precision and recall, ensuring both high accuracy and coverage in detecting commercials.
2. **Real-time inferencing**
- I will use OpenCV to evaluate real-time performance of the models. This ensures that our model's performance is evaluated under conditions similar to those it will encounter in deployment.
This code snippet illustrates how the model will be assessed in real-time, focusing on both **detection accuracy** and **frames per second (FPS)** as the primary evaluation metrics.

Model Execution on BeagleBone AI-64
=====================================
BeagleBone AI-64 Linux for Edge AI supports importing pre-trained custom models to run inference on target. Moreover, Edge AI BeagleBone AI-64 images have TensorFlow Lite already installed with acceleration enabled.
The Debian-based SDK makes use of pre-compiled DNN (Deep Neural Network) models and performs inference using various OSRT (open source runtime) such as TFLite runtime, ONNX runtime etc.
In order to infer a DNN, SDK expects the DNN and associated artifacts in the below directory structure [7].
.. code-block:: text

├── param.yaml

├── artifacts
│ ├── 264_tidl_io_1.bin

1. model: This directory contains the DNN being targeted to infer.
2. artifacts: This directory contains the artifacts generated after the compilation of DNN for SDK.
3. param.yaml: A configuration file in yaml format to provide basic information about DNN, and associated pre and post processing parameters.
Therefore, after choosing the model to be used in GStreamer pipeline, I will generate the artifacts directory by following the instructions mentioned in TexasInstruments:edgeai-tidl-tools examples [7].
.. image:: Assets/Figure4.png
:alt: TFLite Runtime
.. centered::
The data flow in the GStreamer pipeline at a high level can be split into 3-parts [8]:-
1. Input Pipeline - Grabs a frame from the input source.
2. Output Pipeline - Sends the output to the display.
3. Compute Pipeline - Performs pre-processing, inference and post-processing.
I will create a GStreamer Pipeline that will receive input from an **hdmi source** and it will grab it frame by frame. The frame will be split into two paths.
The “analytics” path normalizes the frame and resizes the input to match the resolution required to run the deep learning model.
The “visualization” path is provided to the post-processing module which does the required post process required by the model.
If a commercial video is detected, we apply blurring to the video frames and replace the audio.
If a non-commercial video is detected, proceed with the normal visualization process without blurring or replacing the audio.
Post-processed output is then sent to display [8].
NNStreamer provides efficient and flexible data streaming for machine learning
applications, making it suitable for tasks such as running inference on video frames.
So, I will use NNStreamer elements to do inferencing of videos.

Figure 5: GStreamer Pipeline [8]
The above GStreamer pipeline is a demo pipeline inspired from edge_ai_apps/data_flows [8] and there could be a few more changes to it depending upon our specific need.
- **"hdmisrc"** element is used for capturing audio and video data from an HDMI source.
- **"videoconvert"** ensure proper format conversion for display.
- **"tiovxcolorconvert"** is used to perform color space conversion.
- **"tiovxmultiscaler"** is used to perform multi-scaling operations on video frames. It allows us to efficiently scale the input frames to multiple desired resolutions in a single step.
- **"tiovxdlpreproc"** is used to perform pre-processing of input data in deep learning inference pipelines using TIOVX (TI OpenVX) framework.
- **"kmssink"** is used for displaying video on systems.
