real time human activity recognition

Hi all

I am trying to find human activity (Sitting, Standing, Lying) by a single fixed camera, the work should be in a real time.

can I get your help about which method could be the fastest and more accurate in Matlab??

I am going to detect the human at first and then trying to choose a good method for analysis and find out the activity.

wish to get help from you.

appreciate that ..

This, especially in real-time, seems flabberghastingly difficult.

Perhaps you could do something like train a neural net on previous frames you've already categorized? Matlab has a big neural net toolbox:

It is not possible to do accurate human detection using only a single visible-wavelength camera. See for example http://uk.mathworks.com/matlabcentral/answers/39545-detect-a-human-figure-in-a-live-video#answer_49322 and expand all of the comments.
