: It reduces file size by discarding data that the human eye is less likely to notice, particularly in high-frequency areas of an image.

Generating Image Adversarial Example by Modifying JPEG Stream 1_083.jpeg

: Researchers use algorithms like Discrete Cosine Transform (DCT) to embed bits of information within the JPEG stream without changing the visual appearance. : It reduces file size by discarding data

Every JPEG contains hidden metadata known as (Exchangeable Image File Format). : This can include the camera model, exposure

: This can include the camera model, exposure settings, GPS coordinates, and the exact time the photo was taken.

In the realm of AI, images like this are often part of large datasets used to train models.

: 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
