In general, we seek to convert a grayscale image to a binary image, where the pixels are either 0 or 255. A simple thresholding example would be selecting a threshold value T, and then setting all pixel intensities less than T to 0, and all pixel values greater than T to 255. meridian apartments las vegas nv
