WitrynaNext, you need to determine a threshold to use to convert the grayscale image to a binary image. I suggest the function graythresh, which will compute a threshold to plug into im2bw (or the newer imbinarize). Here is how I would accomplish what you are doing in your example: WitrynaThe graythresh function in MATLAB is used to determine the threshold level for a grayscale image, but it cannot be used directly on an indexed image. ... % Convert the grayscale image to a binary image using the threshold level BW = imbinarize(I,level); % Display the binary image imshow(BW) ...
