Why in the binary image when the image values are just 0 or

Why in the binary image, when the image values are just 0 or 1 we can see just black image. And if we change the values of 1 to 255 we can see some white spots?! Explain that?!

Solution

Please note that, in binary image, when the image values are just 0 or 1, the image is black and white. The binary image is represented by a m*n matrix, with the value for each pixel being 0 or 1. 0 corresponds to black colored pixel and 1 corresponds to white colored pixel. Thats why binary images dispay just 2 colors black and white. RGB image is represented by m*n*3 matrix. Each pixel has 3 values for (R,G,B) intensities. These values are in the range 0 to 255. As, RGB images store the exact content of Red, Green and Blue color, we can view the real, exact and clear image.
