Explore MATLAB source code curated for "IDCT" with clean implementations, documentation, and examples.
This method compresses images using 2D-DCT, transmits them through QPSK modulation and AWGN channel coding, then reconstructs the original images via IDCT decompression - applicable to any image format with configurable compression and transmission parameters.
Image transformation techniques involving 8x8 block partitioning, Discrete Cosine Transform (DCT) for compression encoding, and Inverse DCT (IDCT) for decompression, with code implementation insights
MATLAB implementation of information sequence embedding and extraction using DCT and IDCT transforms for digital images
A video watermark embedding program based on DCT coefficients that reads YUV files, extracts multiple frames, performs DCT transformation on each frame, modifies mid-low frequency coefficient values, applies inverse DCT, and reconstructs frames into YUV format for playback.
