how to make classification for video

I have a scenario and I need to classify it how can I do that?

[Jayaram Theegala]

Can you elaborate more on what you are trying to achieve? Also, provide some information about the features you have extracted from the video and how you want to classify those?

What i want to do to detect the face from the video and then extract the features (anger, sad , nutral) I know that i have to divide the video into frames but i don't know how to classify it

[Jayaram Theegala]

For detection of face, you can use functions from Computer Vision System Toolbox. You can take a look at the following MATLAB documentation for more information:

I need to do classification between the breeding and non-breeding fish from the captured videos using CNN in matlab. But i dont know the steps and what to do for doing classification on vodeos. So can u tell me the simplest way to perform classification on videos.

How do i classify videos using SVM (support vector machine) in matlab? I need to classify human's activities eg: running, walking, etc.. where do i get the example of coding?

One option is to use CNN and LSTM. The below is a demo of video classification which may relate to your study.

The image features were extracted via a pre-trained network and the time-series features were classified using LSTM (Long Short Term Memory).
