I am looking for advice on algorithms that would allow me to recognise an image patch of a specific object. So given an object, I would like to extract patches that would belong to that object (those will be positive patches). Everything else would be negative patches.

My target application is to distinguish a hand (of any hand shape) from other objects without using colour, by being able to identify if a patch belongs to a hand.

For example, I had this in mind,

If I was to identify eyes as my target object, then a patch that contains an eye would be positive and everything else negative. The only problem with a hand, unlike an eye, is that a hand take many hand shape forms.

Are there any suggestions or algorithms that I can use to identify hands in an image?

Thank you in advance.
