WebMar 28, 2006 · IMOVERLAY Create a mask-based image overlay. OUT = IMOVERLAY (IN, MASK, COLOR) takes an input image, IN, and a binary image, MASK, and produces an output image whose pixels in the MASK locations have the specified COLOR. IN should be a grayscale or an RGB image of class uint8, uint16, int16, logical, double, or single. WebSep 20, 2024 · A possible approach is load image, convert to grayscale, Gaussian blur, threshold to obtain a binary image, morph open to remove small noise, find contours, and sort from largest to smallest contour area, the largest contour should be your desired object. Then simply draw this contour with white onto a black mask image to get your result – …

WebThis image is a binary image of a disk after thresholding. Figure 2.50 shows the familiar grayscale image of zebras. When Figure 2.49 is used as a mask to only keep the pixels of Figure 2.50, where the corresponding pixels of Figure 2.50 are white, we end up with the result shown in Figure 2.51. Let's break this down.
