Foveated Video Demonstration
Sanghoon Lee & Alan C. Bovik
Foveation-based Error Resilience
Transmission rate 64 Kbits/sec, QCIF carphone
image (176x144)
Target frame rate 15, Packet loss rate 40%
The PSNR (FPSNR) in the regular video before
error concealment : 17.60 (18.43) dB
The PSNR (FPSNR) in the foveated video before
error concealment : 16.46 (18.75) dB
The PSNR (FPSNR) in the regular video after
error concealment : 26.37 (25.52) dB
The PSNR (FPSNR) in the foveated video after
error concealment : 27.85 (28.45) dB
Very low bit rate foveated video coding for
H.263
Transmission rate 29.3 Kbits/sec for the P pictures
and 354 Kbits for the first I picture
The FPSNR for the regular video : 29.99 dB and
the FPSNR for the foveated video : 33.63 dB
