How to identify objects in a black and white image
I want to go over a black and white picture and see if it has a certain shape.
I know what shape should be more or less the size of the pixels. But I do not know what color her in the picture will be in gray-scale.
How can you check for a shape of a certain size and limit it to a certain level of gray tint?
it probably gets better, if you add your image, and explain, what you're looking for there, specifically.
also, what have you tried before ?
