Local Contrast Segmentation to Binarize Images
—In this paper, a new binarization algorithm for degraded document images is proposed. The method is based on positive and negative pixel energies using the Laplacian of an image...

A perceptual framework for contrast processing of high dynamic range images
Image processing often involves an image transformation into a domain that is better correlated with visual perception, such as the wavelet domain, image pyramids, multi-scale con...

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...

Adaptive local contrast enhancement for the visualization of high dynamic range images
In this paper, we present a new tone mapping algorithm for the display of high dynamic range images, inspired by adaptive process of the human visual system. The proposed algorith...

Natural contrast statistics and the selection of visual fixations
In this paper we address the problem of visual surveillance, which we define as the problem of optimally extracting information from the visual scene with a fixating, foveated ima...
