Q Thresholding is a basic step to convert a gray scaled image into a binary image using a specific threshold value. To find this threshold value is the most critical part. Assume that we have designed a basic algorithm to calculate adaptive threshold Algorithm for computing is
Use initial threshold to put input image gray levels into two bins classes
Compute Global mean for whole image, local means and and scatters and : for both bins
Compute between class mean and scatter using and abs
Compute new using
Repeat steps to find such which maximizes the product of and
You are given a image in fig Assume initial Run one iteration of above mentioned algorithm to find and draw binary image after first iteration. Show all steps of your processing.
