Part2. PSNR/Bitrate diagrams

Contents

  • Part1. Introduction
  • Part2. PSNR/Bitrate diagrams
  • Part3. Additional testing
  • Part4. Final part
  • Y-PSNR/Bit rate, Delta-Y-PSNR/Bit rate, U-PSNR/Bit rate and V-PSNR/Bit rate diagrams

    These diagrams clearly show the dependency dynamics of the compressed sequence quality from its size. Coordinates of the graph basic points are represented by the average PSNR values for the whole sequence and frame sizes. So each graph branch contains ten points that correspond to different bit rates.

    Delta Y-PSNR are the diagrams of comparative PSNR values. DivX 5.1.1 is selected as a reference codec. Each point on a graph represents difference between point on codec PSNR graph and possibly interpolated DivX 5.1.1 PSNR value on this bit rate value.

    Bankomatdi sequence

    Picture 17.    Delta Y-PSNR. Sequence bankomatdi

    Picture 18.    U-PSNR. Sequence bankomatdi

    Picture 19.    V-PSNR. Sequence bankomatdi

    Conclusions:

    • DivX codec is worse than H.264 codecs on the low bit rates.
    • Ateme codec has shown best results on the average and high bit rates.
    • Diagrams are similar for U and V components.

    Picture 22.    U-PSNR. Sequence battle

    Picture 23.    V-PSNR. Sequence battle


    Conclusions:

    • DivX codec is much worse than Videosoft, Fraunhofer and Ateme codecs on the low bit rates.
    • Ateme codec is the best on the average and high bit rates.
    • Diagrams are similar for U and V components.

    Picture 26.    U-PSNR. Sequence bbc3di

    Picture 27.    V-PSNR. Sequence bbc3di

    Conclusions:

    • DivX codec is much worse than the other codecs except Moonlight on the low bit rates.
    • Ateme and Videosoft codecs are the best on the average and high bit rates.
    • Diagrams are similar for U and V components.


    Foreman sequence

    Picture 29.    Delta Y-PSNR. Sequence foreman

    Picture 30.    U-PSNR. Sequence foreman

    Picture 31.    V-PSNR. Sequence foreman


    Conclusions:

    • DivX codec is much worse than the other codecs except MainConcept on the low bit rates.
    • Videosoft codec is the best on the average and high bit rates.
    • Moonlight, Fraunhofer and Ateme codecs act similarly on the high bit rates.
    • Diagrams are similar for U and V components except for the fact that Fraunhofer showed better result on the V component and AVC showed better result on the U component.

    Susidi sequence

    Picture 33.    Delta Y-PSNR. Sequence susidi


    Picture 34.    U-PSNR. Sequence susidi

    Picture 35.    V-PSNR. Sequence susidi


    Conclusions:

    • DivX codec is much worse than Ateme codec on the low bit rates.
    • DivX codec is the best on the average and high bit rates.
    • Diagrams are similar for U and V components except for the fact that Fraunhofer showed better result on the V component and AVC showed better result on the U component.
