VerifiedThe core algorithm of JPEG image compression is the Discrete Cosine Transform (DCT); images are divided into 8×8 pixel blocks, and after each block undergoes a frequency-domain transform, high-frequency detail information is selectively discarded.74% similarUnverifiedJPEG XL adopts a hierarchical encoding structure based on wavelet transforms, allowing the decoder to first render a low-resolution preview with a very small amount of data and progressively refine the image as more data arrives.72% similarUnverifiedCompared to MJPEG, H.264 uses inter-frame prediction technology to reduce bandwidth usage by more than 80% at equivalent image quality.69% similarUnverifiedVideo compression (such as H.264/H.265) encodes in blocks and leaves faint "halos" or blocky artifacts around high-contrast edges (for example, white digits on a dark background), and these artifacts get framed into the cleanup region along with the digits.69% similar
