How can I detect complete body like hand , leg?

Question

Using CIFaceFeature we can detect face feature. But I want to detect hand and leg too.

How can we detect these? Is there any other classes or logic using which we can detect these.

Answer 1

OpenCV is 'just beginning'. Recognition is hard problem and still remain unsolved at most part. There is no hand/leg detection in openCV. You have to train the data yourself using machine learning algorithm provide by openCV. You have to collect positive data (human body image for example) and negative data (non human body image) in order to train.
