Answers to Questions

What is a random pixels image?

A random image is an image in which the pixels are chosen at random, so they can take any color from the desired palette (generally 16 million colors). The resulting images look like multi-colored noise background.

Example: random-dcode is an image of 256x256 pixels with fully randomized colors (in appearance, see below)

How to detect randomness in a randomized image?

A perfectly random image will have ideally distributed colors (about as much green tint as blue or red, and about as many bright colors as grayish colors), any variation in the average values over a given area tends to indicate non-random values.

Example: By analyzing the image above, the reds are abnormally present in the center of the image because it hides the message: random-dcode-2
