Wavelet Transform and Fourier Transform for Image Processing

The compressed archive contains source code implementations for image compression using Wavelet Transform, Fourier Transform, Hadamard Transform, and Discrete Cosine Transform, along with a program for plotting image histograms and histograms of histogram-equalized images. The implementations include key algorithms for frequency-domain analysis and image compression techniques.

Image Discrete Cosine Transform, Hadamard Transform, and Fourier Transform

Performing discrete cosine, Hadamard, and Fourier transforms on input images. Comparing the frequency spectra of the three transforms and evaluating the reconstructed image quality after inverse transformation with practical implementation approaches.
