: It reduces file size by discarding data that the human eye is less likely to notice, particularly in high-frequency areas of an image.
The JPEG format itself (Joint Photographic Experts Group) is the standard for digital photography due to its efficient .
Every JPEG contains hidden metadata known as (Exchangeable Image File Format).
: Researchers use algorithms like Discrete Cosine Transform (DCT) to embed bits of information within the JPEG stream without changing the visual appearance.
: Developers often use libraries like Albumentations to manipulate these files for machine learning or use scripts to strip metadata to protect user privacy. 4. Machine Learning & Computer Vision

: Conversely, specialized tools like JPEG-GraphNet are designed to detect these hidden messages by analyzing the mathematical patterns (features) of the file. 2. JPEG Compression and Quality
