Basic image processing

Consider linear contrast correction. Given y_min = 10 and y_max = 207, compute value of pixel with y = 54 after correction. Round result to the nearest integer.

For example, if you get 90.5, type 91

You are given images with unknown gamma correction parameters. Choose appropriate gamma for each image. Available gamma values are 0.5, 0.75, 1, 1.5, 2. Type in a comma-separated list of gamma values corresponding to the following list of images. Example of answer: 2, 1.5, 1, 0.75, 0.5

How many convolution operations are needed for canny edge detector?

Imagine that you want to store color images with alpha (opacity) channel. Four numbers are used for every pixel: three color values (R, G, B) from range [0..31] and one opacity value from range [0..63]. How many bits are used for every pixel?
