Compression methods
Compression methods
- Pixel-sequence
- sequences of 1’s, 0’s, , , to count
- (easy for TV-lines, but sequence lengths are limited)
- pattern creation and indexing (Ziff-Lempel)
- (less effective without semantic-based repeats, as in text)
- 2D, 3D Localities
- Preprocessing to frequency domain
- Blocks 8 x 8 pixels (JPEG) for images
- (some storage and latency in encoding)
- Cubes 8 x 8 x 8 (MPEG) for video
- (much storage and latency in encoding)
