WebImage thresholdingis most effective in imageswith high levels of contrast. Matlab Im2bw This MATLAB function converts the grayscale image I to binary image BW, by replacing all pixels in the input image with luminance greater than level with the value 1 (white) and replacing all other pixels with the value 0 (black). ... http://computableplant.ics.uci.edu/sw/segtrack/global/html/imthresh.html
WebNov 6, 2013 · Thresholding is an operation often used to generate black and white images. For this function we’ll also use it to rescale the image so that all of the final values fall in the range 0 to 255. (Although in this case, the output pixels will ONLY be 0 or 255.)
