23 o o o Region of Interest coding principle Region of Interest (ROI) coding allows a non-uniform distribution of quality. The ROI is coded with a higher quality than the background (BG). A higher compression ratio can be achieved with same or higher quality inside ROIs. Static ROIs are defined at encoding time and are suitable for storage, fixed transmission, remote sensing, etc. Commonly referred to as ROI coding. Dynamic ROIs are defined interactively by a user in a client/server situation during a progressive transmission. Suitable for telemedicine, PDAs, mobile communications, etc. They can be achieved by the dynamic generation of layers matching the user s request. 23

24 Lossless ROI mask generation ROI in image domain Final ROI mask 24

25 Encoding ROIs: scaling Original General scaling Maxshift MSB LSB ROI s s o o o o Shift up quantized ROI coefficients by s bitplanes. The value of s is recorded in the codestream header for each ROI. At decoder ROI coefficients are unshifted prior to dequantization. The ROI mask is required at both, encoder and decoder. In maxshift, s is large enough to separate ROI and BG No ROI mask required at decoder ROI <-> BG quality differential not controlled 25

26 ROI Maxshift example ROI 256:1 45:1 (almost all ROI decoded) No ROI ROI covers 5% of image, 2 lowest resolution levels in ROI mask. Magnified portion shown. 26

27 ROI Maxshift example (cont d) ROI 16:1 4:1 (complete decode) No ROI ROI covers 5% of image, 2 lowest resolution levels in ROI mask. Magnified portion shown. 27

28 Error resilience example 16:1 compression ratio. Transmission error rate No errors in codestream header. Magnified portion shown. No transmission errors No error resilience Full error resilience 28

29 Error protection techniques o Coded image data Code-block partition Regular termination of arithmetic coder Segmentation symbols o Packet heads Start of packet markers Packet heads in main / tile codestream header Partition of packets into precincts 29

31 Error resilience visual results Bit error rate = 10-4 JPEG 16:1 CR JPEG :1 CR Images with median quality, of 200 runs 31

32 JPEG 2000 File Format: JP2 o JP2 is the optional JPEG 2000 file format to encapsulate JPEG 2000 codestreams. Extension: jp2 Allows to embed XML information (e.g., metadata) Alpha channel (e.g., transparency) Accurate color interpretation True color and palette color supported Intellectual property information Capture and default display resolution File magic number File transfer errors (ASCII ftp, 7 bit , etc.) 32
