[DIP] Nice and easy dithering algorithm
Sometimes (e.g. newspaper or compressing images) we have to reduce depth of our image to only 1 bit. We can do it simply by applying thresholding: But the result is usually not satisfactory for us – it has large regions of the same color. There is a better idea than thresholding when it comes to monochromatic images: 1. Take original image: 2. Apply gaussian noise: 3. Do thresholding: After this procedure we have an image that creates illusion that it…
