Color Matching with Amplitude Not Left Out
Amplitude for color mixing is different from other amplitudes such as loudness. Color amplitude must refer to a light's ability to look different from other lights, to expres...

Tensor Based Feature Detection for Color Images
Extending differential-based operations to color images is hindered by the multi-channel nature of color images. The derivatives in different channels can point in opposite direct...

Mathematical Discontinuities in CIEDE2000 Color Difference Computations
We examine mathematical properties of the CIEDE2000 color difference formula and illustrate that the CIEDE2000 color difference is not a continuous function of the CIELAB color pa...

Measuring the Relationship between Perceived Image Contrast and Surround Illumination
While an image's relative surround luminance increases from dark to light, the perceived contrast of the image will increase. For this reason, projected transparencies are ma...
