Activity recognition using sift or hog

Hi All,

I need to do activity recognition using SIFT or HOG or motion SIFT. I searched everywhere but I could not get an inkling about how to go about it or is this even possible? Can someone please point me in the right direction? I am pretty keen to use matlab only for this.

Thanks in advance Mehwish

Hi @Mehwish,

For activity recognition, it would not be a good idea to use SIFT or HoG. It would be better to use "signalTimeFeatureExtractor" in MATLAB combined with machine learning to perform the same.

Please refer to the below documentation link on "Human Activity Recognition Using Signal Feature Extraction and Machine Learning". This will assist you with the task at hand.

You can also refer to the below link, which does activity recognition using the Optical Flow data.

Hope you find this information helpful!
