This is an image contrast enhancement algorithm that overcomes limitations in standard histogram equalization (HE). The two primary features is adaptive HE (AHE), which divides the images into regions and performs local HE, and the contrast limited AHE (CLAHE), which reduces noise by partially reducing the local HE. Bilinear interpolation is used to avoid visibility of region boundaries.

If the input is a bandlimited signal containing components at DC - 0.5Fs where Fs is the sample rate, SINCRESAMPLE will return the signal that would have been seen with a higher sampling rate (and the same filter settings). The algorithm depends...
The program will compare the original image of a vehicle and the image taken after collision has occurred. The comparison will find the dents in the vehicle and highlight the boundaries. The code is developed to find the dents in an insured...
ImHuman is a new way of asking "are you a human?" question to your website visitors. It is designed to be easy, fun, secure and user friendly than most of the other captcha systems. Security and fun grows a little bit more everyday...
Shows y-values of time series in 2D plots by clicking on the axes.
A quick test can be done by typing showYs('example') after the file is placed in the Matlab path
It works with one or multiple curves. By...
This function shows an approximation of the Julia set boundary for the functions of the form P(z) = z^2 + C. The inverse iteration is a method for calculating previous values of z by doing z = sqrt(z-c). By doing this, points along the boundary...
WORLDDATAMAP wraps the Mapping Toolbox function WORLDMAP (version 2.1 and higher) and adds data to the map. The data may consist of vector data from shapefiles or surface data from a regular data grid. The displayed vector data depicts boundaries...
This collection of M-files takes as input a close-up image of the human iris and returns as output the original image overlaid with circles corresponding to the pupil and iris boundaries.In addition it returns the centre and radius coordinates of...
The icoshift tool for Matlab is an open source and highly efficient program specifically designed for solving signal alignment problems in metabonomic NMR data analysis, but it can also properly deal with other spectra-like datasets (e.g. data...
This simulink model simulates the damped driven pendulum, showing it's chaotic motion. theta = angle of pendulum omega = (d/dt)theta = angular velocity Gamma(t) = gcos(phi) = Force omega_d = (d/dt) phi Gamma(t) =...
The Mandelbrot set is a set of complex numbers C where z_n+1 = z_n^2 + c (z_0 = 0) does not diverge for all c in the set C. The image is generated by calculating the number of iterations until |z_n| is larger than a certain escape radius. Of...
The bootstrap is a way of estimating the variability of a statistic from a single data set by resampling it independently and with equal probabilities (Monte Carlo resampling). Allows the estimation of measures where the underlying distribution is...
Carries out Gaussian smoothing followed by differencing as a way of estimating the gradients of a grey-level image in the X and Y directions. This is the initial stage of the well-known Canny edge detector, but the gradients can be used for many...
Description of GAME: Objective: Divide the Pentomino into 4 Congruent Parts. STEP 1: Select any of the Pentomino Links by clicking on it. STEP 2: Start selecting the Sub-Links to draw boundaries of divided Pentomino. Note: Not...
