Contrast

GUI control to allow user to input a scalar. The callback is called continuously as the user steps the spinner. For example if the value was contrast in an image-processing application, the image could update as the user presses on the control.

LYAPACK is a MATLAB toolbox for the solution of certain large scale problems in control theory, which are closely related to Lyapunov equations. In contrast to the 'lyap' and 'dlyap' command in the MATLAB Control toolbox it uses iterative algorithms and is intended for large, sparse problems.

Calculates Average Roughness, RMS Roughness, Skewness and Kurtosis. Has an option of filtering low-frequency and high-frequency components of images and calculating roughness for each of the separated images (waviness and roughness components).Has an option to apply PCA model to roughness...

It is a known fact that human beings are more sensitive to edges (contours). It is expected that an enhanced image should have more edge pixels than the original image and this parameter of EBCM does measure the intensity of edge pixels in small windows of the image.Ref: A. Beghdadi and A. L....

Function HISTF ('flexible histogram') extends Matlab's HIST by letting one bound displayed percentiles, set x-axis limits and y-axis maximum, set x bin size, and draw a marker line at given x position. In contrast to HIST, relative rather than absolute frequencies are displayed. (Note: when range...

This m-file produces a colorbar with solid blocks of color between the contour levels that correspond precisely to the colors in the filled contour plot. This is in contrast to the standard MATLAB colorbar which simply plots all the colors in the colormap and, therefore, only approximates what is...

An API to generate a full color scheme from a base color. Generates a palette of background and foreground colors. Foreground colors are generated so they have enough contrast to be readable against the background color. Also includes functions to brighten, darken, and mix colors.

The Principles of Ambiophonics*: 1.) Ambiophonics uses RACE* (Recursive Ambiophonic Crosstalk Elimination) to enable binaural listening 2.) The Speakers are positioned with a separation angle smaller than 20?*A* (called Ambiodipol) instead of 60?*A* used in stereo. No worries, in contrast to...
