We present a technique in which statistical methods are used to estimate the tone level of the paper. This estimate is used to set the parameters for a tone reproduction curve. The technique is incremental, the statistical data is gathered during the scan. While the scan progresses, the estimate is refined based on the increased amount of data avail able from the accumulated histogram. This has...

We propose a novel video colorization method based on sparse optical flow and edge-oriented color propagation. Colorization is a process of adding color to monochrome images or videos. In our video colorization method, it is assumed that key frames are appropriately selected out of a grayscale video stream and are properly colorized in advance. Once key frames are colorized, our method colorize...

This research focuses on the discriminatory experiences that young African American women in South report as a function of their actual and perceived skin tone. Participants (N = 76) were given Pantone Skin Tone guide (Pantone, 2017) asked to find best color (varying undertone lightness) matched closely Following that, an experimenter identified participants’ tone they completed several questio...

Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the behavior of tone-mapping operators, we model their mechanisms by fitting a generic operator to an HDR image and its tone-mapped LDR rendering. We demonstrate that the majority of b...

HIS color space is based on the visual features of our eyes, and uses tone, brightness, saturation to manifest the color. While conducting edge detection on color images, in order to get better effects and consistent with human visual perception, a novel HIS-like color space is defined and it is obtained in the process of the improving HIS color model. Edge detection has been made on image whic...

When viewing images on a monitor, we are adapted to the lighting conditions of our viewing environment as well as the monitor itself, which can be very different from the lighting conditions in which the images were taken. As a result, our perception of these photographs depends directly on the environment in which they are displayed. For high-dynamic-range images, the disconnect in the percept...
