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
