  4. JNDmetrix-IQ Analysis Results 3D-SPIHT (ERC-SPIHT) VIDEO QUALITY MEASUREMENT DATA 3D-SPIHT IMAGE ORIGINAL FRAME 175 DISTORTION MAP MAXIMUM DISTORTION LEVEL JND VALUES 240 FRAMES

  5. JNDmetrix-IQ Analysis Results MPEG-2 VIDEO QUALITY MEASUREMENT DATA MPEG-2 IMAGE ORIGINAL FRAME 3 DISTORTION MAP MAXIMUM DISTORTION LEVEL JND VALUES 240 FRAMES

  6. JNDmetrix-IQ Analysis Results 3D-SPIHT (ERC-SPIHT) VIDEO QUALITY MEASUREMENT DATA 3D-SPIHT IMAGE ORIGINAL FRAME 175 DISTORTION MAP MINIMUM DISTORTION LEVEL JND VALUES 240 FRAMES

  7. JNDmetrix-IQ Analysis Results MPEG-2 VIDEO QUALITY MEASUREMENT DATA MPEG-2 IMAGE ORIGINAL FRAME 236 DISTORTION MAP MINIMUM DISTORTION LEVEL

  8. Corrupted Video Sequences 3-D SPIHT vs. MPEG-2 3-D SPIHT MPEG-2 VIDEO QUALITY MEASUREMENT DATA Frame 156:179 Frame 1:24

  9. JNDmetrix-IQ Analysis Results 3D-SPIHT (ERC-SPIHT) vs. MPEG-2 VIDEO QUALITY MEASUREMENT DATA

  10. Video Sequences Original vs. 3D-SPIHT ORIGINAL 3D-SPIHT

  11. Video Sequences Original vs. MPEG-2 ORIGINAL MPEG-2

  12. CONCLUSION Superior Performance of Error-Resilient 3-D SPIHT over MPEG-2 ERC-SPIHT Interleaved tree blocks provide • Error resilience/recovery • Coding efficiency MPEG-2 with FEC Burst of packet erasures or decoding failure
