Abstract

The human visual system (HVS) is robust to changes in viewing conditions, such as variations in illumination and viewing distance. Not all elements of our perception stay constant, for example the way we perceive brightness is highly dependent on the background luminance and threshold contrast strongly depends on signal frequency. However, suprathreshold contrast is considered to be constant across viewing conditions and stimuli, the property known as contrast constancy. We intend to verify whether this holds true for a wide range of luminance levels. Results of such measurements could be used to better reproduce images on displays of varying brightness.

A contrast enhancement method using dynamic range separate histogram equalization

In this paper, a contrast enhancement method using dynamic range separate histogram equalization (DRSHE) is proposed. Histogram equalization (HE) method is widely used for contrast enhancement. However, HE is not suitable for consumer electronic ...
Color constancy by learning to predict chromaticity from luminance
NIPS'15: Proceedings of the 28th International Conference on Neural Information Processing Systems - Volume 1

Color constancy is the recovery of true surface color from observed color, and requires estimating the chromaticity of scene illumination to correct for the bias it induces. In this paper, we show that the per-pixel color statistics of natural scenes—...
Perceptually motivated automatic color contrast enhancement based on color constancy estimation
Special issue on emerging methods for color image and video quality enhancement

We address the problem of contrast enhancement for color images. Our method to enhance images is inspired from the retinex theory. We try to estimate the illumination and separate it from the reflectance component of an image. We use denoising ...
