Detailed Description

C Optimized Median NxN Kernel Convolution

This function blurs the image by changing the color of the pixel being looked at to the median value of the current pixel and the pixels surrounding it. The number of surrounding pixels is defined by the kernel size parameter. If kernel is 3, then the pixel being looked at is the center of a 3x3 box. Valid kernel sizes for this function are odd integers greater than 0. The larger kernel sizes cause execution time to slow at an exponetial rate.

Supports the following formats:

• phImageRGB24
• phImageHSV24

Todo:

add example image inputs and processed image outputs

add example application code that shows how the processed images were output
