Textures

An Image that is generated with texture synthesis has a distribution of local patterns. Given this image below, where the color of the pixel under the red box with the X is unknown.

? a) How many pixels (other than X) have a 3x3 neighborhood that matches the neighborhood of the 3x3 neighborhood of X?

? b) What is the probability of X being Dark given its neighborhood in question 2a?

? c) How many neighborhoods match if the neighborhood consists only of the four pixels above, below, left and right of X?

? d) What is the probability of X being Dark given its neighborhood in question 2c?
