Image Processing

The objective of this project was to end up with a GUI application that would perform various operations on images and pairs of images. Ranging from simple color inversion, to noise removal algorithms and fourier transforms.

Adding

Example of adding two images together

Various Operations

In this image you can see the original image, then the image after changing 95% of the image for noise and attempting to remove it. Beside that is the image after a sobel filter, and finally a gaussian blurred version

Fourier Transform

Fourier power spectrum computed from the image on the left

Histogram

Histogram displaying number of pixels with the given r,g,b values

For purposes of simplicity, and since that wasn't the goal of the assignment, for image loading we went with the PPM Image Format, a very simple , human readable and uncompressed image format.
