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: Witryna21 lut 2024 · the imbinarize function takes a grayscale image and automatically sets a threshold, all gray values below it are set to zero and all values above it are set to one. it becomes a purely black and white image, no gray scale, that segments light objects from dark background in your original image.
