­Welcome to the Dataset of Colour Contrast, Matlab and C++ Programs for Image Retrieval!


CIE tristimulus values measured by Minolta Chroma Meter CS-100A


+ All-data including


-       xyY-values for 16 backgrounds and reference white and reference-colourfulnese

-       Mean subjective estimations of 30 test samples under each background

-       Predictions by CAMcc


+ Matlab programs of CAMcc for processing images featuring


-       Processing images in group

-       Select parameters to be compared, i.e., lightness, colourfulmess and hue

-       Run the demo program to retrieve images.


-       Download Matlab programs (85 mBytes) including all images (in the folder of ‘Image/’.


-       Download Visual C++ programs (9 Mbytes) including all data to compare subjects’ data and CAMcc predictions (in the folder of CAMcc/Data’.
