A C program that allows the user to input a PNG image through command line and select how they want to manipulate that image.

Using the provided Makefile, the user can compile using gcc/ clang and run the resulting "process" executable. Running "./process" on the command line will allow the user to:

• Generate a density histogram for the image.
• Generate a cumulative histogram for the image.
• Improve the image's contrast.
• Resize an image's width and height by certain factors.
• Rotate an image by some angle (igradient_filtergradient_filtern degrees).
• Perform histogram equalization on the image.
• Rotate the image's hue.
• Increase the image's color saturation.
• Increase the image's intensity.
• Perform low-pass filtering on an image using a kernel.
• Perform high-pass filtering on an image using a kernel.
• Perform low-pass or high-pass filtering using a Fourier transform.
• Create a gradient image that accentuates changes in color based on the given image.
• Clean up an image using a median filter.
• Detect edges in an image.
