Abstract:
1. A method for image segmentation comprising: obtaining an image including a two dimensional (2D) sensing information including a plurality of one dimensional (1D) sensing information, each 1D sensing information being arranged in parallel with a first axis, and each 1D sensing information representing a plurality of values arranged in parallel with a second axis; segmenting the image into groups each corresponding to touch or proximity of at least one external conductive object, each group including a plurality of line pieces in a plurality of 1D sensing information continuously arranged in parallel, wherein each line piece has a plurality of values continuously arranged in parallel; calculating the mass of each line piece of at least one group, wherein the masses in the same group are continuously arranged in the second axis, wherein the mass of each line piece is calculated based on the plurality of values of each line piece; and determining line pieces corresponding to touch or proximity of each external conductive object based on the calculated masses of each group, wherein the masses corresponding to each external conductive object are arranged continuously, at least two masses at one side of the plurality of masses corresponding to each external conductive object are arranged in an increasing order, and at least two masses at the other side of the plurality of masses corresponding to each external conductive object are arranged in an decreasing order.
