Gaussian thresholding

WebThresholding is an image segmentation process, where a function is applied to the pixels of an image to make images easier to analyze. The pixels of the image are assigned a value in relation to the threshold function provided. Thresholding is the way of selecting areas of interest of an image while ignoring the parts we are not concerned with.
