Vulkan/CUDA/HIP/OpenCL/Level Zero/Metal Fast Fourier Transform library

Serveral digital image watermark algorithms implement with C++/OpenCV

🖼️ 🕵️ Forgery Detection on Images

DCT-based image denoising algorithm

2D DFT and 2D DCT of images

The program implements forward and inverse version of 2D Discrete Fourier Transform (FFT), Discrete Cosine Transform, Discrete Walsh-Hadamard Transform and Discrete Wavelets Transform (lifting scheme) in C/C++. The output of transforms is displayed for a given input image.

Image Compression using Huffman Coding

Renewed DCTFilter filter for VapourSynth (with arbitrary sized DCT and github actions based static build for Windows)

Create image manipulation techniques e.g. resizing to half , color conversion. And also providing the JPEG compression technique from the first step which is performing the DCT and the Zigzag and RLE(run length encoding) and the inverse for each one, all written in c++.
