Dithering

This tool has been created in order to show the dithering effect: the addition of signed noise to the image before quantization can improve the appearance of the result. Use noise to reduce quantization error.

The application allows the user to choose the number of colors by which the image will be composed.

Once the number of colors has been selected and the accept button has been pressed, two new tabs will open: one showing the quantized image without usin dithering and the othre applying dithering.
