Signal-to-Noise Ratio Before and After Image Transformation

This program computes and returns the signal-to-noise ratio (SNR) before and after image transformation, requiring only the input of an image filename to generate results

DCT as a Separable Image Transform for Compression

This implementation demonstrates image compression using 8x8 block-based Discrete Cosine Transform (DCT) and reconstruction via Inverse DCT (IDCT): DCT serves as a separable transform for image compression encoding, while IDCT handles decompression. The process involves dividing images into blocks, applying mathematical transformations, and reconstructing with minimal quality loss.
