System features

System Features

  • Motion-Compensated JPEG 2000

    • Combines the versatile motion compensated temporal filter with an industry standard JPEG 2000 codec.

    • Scalable wavelet/subband coding is performed both temporally and spatially.

  • Hierarchical MC-JPEG 2000

    • Codes up through the desired resolution level, eliminating the need to process unneeded higher resolutions.

    • Closed-loop system is an extension of MC-JPEG 2000.

    • Open-loop system eliminates the embedded decoder, reducing the complexity of the encoder.
