Act as a Video Analytics Expert and answer the below questions$-$Q$3.$ Implement the video processing technique used in any one published journal for video processing with Tensorflow$/$Keras code Q$4.$ Implement the DL learning algorithm$/$technique for the journal chosen in Q $3$ with Tensorflow$/$Keras code and compare the results. Include the following in the beginning of the Notebook.

One sentence for the task or application to be achieved

Video processing technique used

Performance metric used, including the equations.

Journal URLs for Q$3$ and Q$4$

List all the dependencies necessary for running the code and specify their versions, in the very beginning of the notebook. Compare the results of Q$3$ and Q$4$ according to the chosen performance metric.

Compare the time taken to execute the code.
