A technique where a message is embedded into a JPEG image in such a way that the original image can be perfectly restored after the data is extracted.

Researchers aim to reduce "bitstream expansion," often citing specific bit counts (e.g., reductions of 1038 to 2243 bits) to prove the efficiency of their methods. Typical Research Workflow

The content typically visualizes the transition from an uncompressed RGB image to the YCbCr color space, followed by Discrete Cosine Transform (DCT) and quantization. 1_038.jpeg

Plotting PSNR (Peak Signal-to-Noise Ratio) against payload size to measure quality.

Advanced algorithms use these metrics to determine which parts of an image can hide data with the least amount of visual distortion or "file expansion". A technique where a message is embedded into
