Summary:A method for detecting an arbitrary number of touches from an input image of a multi-touch device comprising the following steps: -processing said input image and obtaining a processed image; -segmentation by thresholding of said processed image (8000) and obtaining a segmented image; -identifying regions of the segmented image; -finding local maxima, each local maximum being of size one pixel on a sub-region inside each region; -determining at least one touch position based on said local maxima.
