pnmpack-test

Description

This is the packaged version "Images for testing the limits of compression algorithms".

To unpack, use pnmpack or packPNM.

test images

These are provided by Thomas Richter [email protected] with these descriptions:

honolulu.zip:

This is the "honolulu test set", a couple of structurally challenging images. They easily loose structure due to compression and have been found useful for testing. The images are copyright Olivier Pfeiffer, available under CC-nc-by license. A release is inside.

bird_of_paradise.ppm honolulu_cathedral.ppm honolulu_zoo.ppm oahu_northcoast.ppm oahu_waimea2.ppm oahu_waimea.ppm waikiki_at_night.ppm

hdcompare.zip:

This is the HDPhoto test image set, provided by Microsoft. It contains a couple of interesting stress images for compression purposes. A formal release is inside. Please note that I believe that MS probably optimized HDPhoto aka JPEG XR a bit too much for this test set as it performs a bit weaker on other image sets.

p01.ppm p02.ppm p03.ppm p04.ppm p05.ppm p06.ppm p07.ppm p08.ppm p09.ppm p10.ppm p11.ppm p12.ppm p13.ppm p14.ppm p15.ppm p16.ppm p17.ppm p18.ppm p19.ppm p20.ppm p21.ppm p22.ppm p23.ppm p24.ppm p25.ppm p26.ppm p27.ppm p28.ppm p29.ppm p30.ppm

richard.zip:

This is a small test set of images of higher dynamic range provided by Richard Clark (former web master of SC29 WG1).

P8110095.ppm P9010454.ppm P9030485.ppm P9040558.ppm P9040559.ppm P9040563.ppm P9140581.ppm PB101110.ppm

core1.zip:

This is a subset of the above image sets, namely the "AIC core 1 test image set" that has been selected for subjective evaluation. This test image set contains images that are easily degraded by compression and thus more critical than other images. It is a subset from the Honolulu set and the HDPhoto set.
