Spatial filters assign the value of a pixel based on their neighbors. Filters are defined as matrices, known as kernels, and are applied to an image through an operation known as a convolution.

The image being used for this post is a rgb2gray converted lena image. Each kernel is a…

A dark image and its color intensity distribution

The previous post introduced the distribution plots of the channel values. Let us consider this dark image. The histogram of the channel values shows that most pixels have low intensity values. We want to make this distribution uniform, which is equivalent to making the CDF (blue) linear (red).
