  7. VISUALLY LOSSLESS CODING Currentmethods: focused on theencodingprocess Researchpurpose: extract a visuallylosslessimagefrom a JPEG2000 codestream JPEG2000 codestream LIFE-VISION

  8. EMBEDDED QUANTIZATION W 0 LIFE-VISION

  9. EMBEDDED QUANTIZATION W 0 uniform scalar deadzone quantization (USDQ) LIFE-VISION

  10. EMBEDDED QUANTIZATION emit 0 emit 1 W 0 bitplane coding (BPC) LIFE-VISION

  11. EMBEDDED QUANTIZATION 0 0 1 1 W 0 bitplane coding (BPC) LIFE-VISION

  12. EMBEDDED QUANTIZATION 0 0 0 0 1 1 1 1 W 0 bitplane coding (BPC) WHY IS USDQ+BPC SO POPULAR ? 1) is convenient for current hardware 2) achieves competitive coding performance 3) many works aimed to improve efficiency IS USDQ+BPC OPTIMAL FOR LOSSY IMAGE CODING ? LIFE-VISION

  13. EMBEDDED QUANTIZATION emit 0 emit 1 W W 0 0 GENERAL EMBEDDED QUANTIZATION (GEQ) T1 LIFE-VISION

  14. EMBEDDED QUANTIZATION 0 1 W W 0 0 GENERAL EMBEDDED QUANTIZATION (GEQ) T1 T2 LIFE-VISION

  15. EMBEDDED QUANTIZATION 0 1 W W 0 0 GENERAL EMBEDDED QUANTIZATION (GEQ) T1 T3 T2 LIFE-VISION

  16. EMBEDDED QUANTIZATION W W 0 0 GENERAL EMBEDDED QUANTIZATION (GEQ) LIFE-VISION

  17. EMBEDDED QUANTIZATION W W 0 0 GENERAL EMBEDDED QUANTIZATION (GEQ) different thresholds: quantizers with K stages: LIFE-VISION

  18. EMBEDDED QUANTIZATION W W 0 0 GENERAL EMBEDDED QUANTIZATION (GEQ) different thresholds: quantizers with K stages: Example: LIFE-VISION
