Rate/Distortion Curves for Different Wavelet Cores

I've ran a bunch of tests with the J2K simulator and posted the rate/distortion curves here. Click on the image to get the corresponding graph.

If you need the numeric data for your own analysis you can get the numbers in the format used by xgraph by clicking the corresponding "numeric data" button. The numeric data has three columns (only the first two being displayed by xgraph):

  1. Actual Bit Rate in bits per pixel
  2. PSNR Distortion in dBs
  3. Requested Bit Rate

Compression Parameters:

Parameter Value
Tile Size 512 x 512
Quantization Tyupe Derived
Quantization Step 0.1324 (Mantissa 121, Exponent 11)
Number of Layers 1
Guard Bits 3
Number of Wavelet Transform Levels 3
