Detecting particular objects in the image i.e image segmentation with opencv

Question

I have to select any particular object visible in my image on i-phone. Basically my project is to segment image objects on the basis of my touch.

The method I am following is to first detect contours of the image and then select a particular sequence based on finger touch. Is there any other method which would be more robust because I have to run it on video frames?

I am using OpenCV and iphone for the project. PLease help if there is any other idea which has been implemented or is feasible to implement.

Answer 1

Have you looked at SIFT or SURF implementations? They both track object features and are resilient (to a certain degree) to rotation, translation and scale.

Also check out FAST which is a corner detection algorithm which might help you, they have an app on the app store showing how quick it is too.
