Need help about Convolution neural network

I am research student and working on human action recognition. I need help in developing code:

• Take input as image (or frame) format (any Matlab readable format)
• Apply CNNs on it (number of layers can be customized)
• Gives output in the form of vector (CNN features) or matrix
• Can run on CPU

I am new in using deep learning techniques.

If you show us what you've tried and ask a specific question about where you're having difficulty we may be able to offer some guidance.

If you have no idea where to start, take a look at the documentation for Deep Learning Toolbox (or Neural Network Toolbox if you're using a release earlier than release R2018b -- it was renamed in that release.)

Thanks for your replay

I want to extrat features of image (frame) on the basics of CNNs and want to use these features for action recognition of video..
