- Normalized Mutual Entropy
- License: Freeware
- Price: 0.00

Normalized mutual entropy provides a measure of the diversity of a two dimensional matrix. It takes mutual entropy and normalizes for the marginal entropy of the variable of interest (column variable in the code). See screen shot or embedded references for formula. This code is used for the estimation of biodiversity in ecological systems, but is not limited to such applications. The code can be used in any system where the diversity of variable interactions is of interest. Please see follow-ups for code written for the inclusion of more than two variables..

- Crosscorelation
- License: Freeware
- Price: 0.00

In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or inner-product. It is commonly used to search a long duration signal for a shorter, known feature. It also has applications in pattern recognition, single particle analysis, electron tomographic averaging, cryptanalysis, and neurophysiology..

- SVD-based Image Quality Measureb
- License: Shareware

This program outputs a graphical & numerical image quality measure based on Singular Value Decomposition. For the given images, Blockwise SVD is taken and image quality measure is derived. For details on the implementation, please refer Aleksandr Shnayderman, Alexander Gusev, and Ahmet M. Eskicioglu, "An SVD-Based Grayscale Image Quality Measure for Local and Global Assessment", IEEE TRANSACTIONS ON IMAGE PROCESSING, VOL. 15, NO. 2, FEBRUARY 2006. Those who are new to Matlab Programming can see the "SampleUsage.m" file for the usage of the script "SVDQualityMeasure.m". Those who are already familiar with Matlab Programming can directly use the script "SVDQualityMeasure.

- Bhattacharyya Distance Measure for Pattern Recognition
- License: Shareware

The m-file provides a tool to calculate the Bhattacharyya Distance Measure (BDM) between two classes of normal distributed data. The BDM is widely used in Pattern Recognition as a criterion for Feature Selection. Directly calculation may result in divide by zero error due to possible (near) singularity of cov(X1)*cov(X2). The improved code uses the Cholesky factorization for the normal cases but uses sqrtm for near singular cases..

- Histogram-based class separability measure
- License: Shareware

The provided functions demonstrate a histogram-based measure for class separability, given the samples from two classes (binary classification problem). The proposed error classification estimation method is described in (B) and it is based on estimating the pdf of each class using histograms. The function that estimates the class seperability method is computeHistError(). Function theoreticalError() computes the theoretical error for two Gaussian distributed classes. Function testClassSeperability() calls the other two functions and displays the results for two Gaussian distributed functions. It has to be noted that computeHistError() can be used for any kind of class distribution, since it estimates the pdf of each class using the histogram method.

- Distance measure from object to camera
- License: Shareware

The objective of this program is to be able to measure distance from an object to the web cam you are using, this measure is given in centimeters(cm). The interface is very simple, it consists of an axes space that lets you visualize what the cam is seeing, the program will draw a rectangle in the outline of the object that it's focusing. You'll be able to see that there also are 2 buttons, one that says 'Start Cam', and the second one 'Distance'. To make the program work you'll need objects that are very white, in my case I used the screen of an ipod touch, I also tried with a paper ball, and a white ruler, but I'm sure that any white object should work as long as you have the right brightness in the room.

Jumble is a handy, very useful Java mutation tool specially designed to enbale developers to measure the effectiveness and coverage of JUnit test suites.
Do you want to know how good your JUnit tests are?
Jumble will tell you: from 0% (worthless) to 100% (angelic!).
Jumble is a class level mutation testing tool that works in conjunction with JUnit. The purpose of mutation testing is to provide a measure of the effectiveness of test cases.
A single mutation is performed on the code to be tested, the corresponding test cases are then executed. If the modified code fails the tests, then this increases confidence in the tests.

- ProDelphi x64
- License: Shareware

ProDelphi x64 is a tool to measure the runtime of programs written in Delphi Object Pascal. First successful industrial usage of ProDelphi was in February 1998. Since then ProDelphi has been permanently improved, also a lot of customer suggestions were integrated.
The principle of source instrumenting, the sophisticated measurement correction algorithm and the granularity of 1 CPU-cycle guarantee an outstanding measurement accuracy. Even very small or multiple nested functions are measured precisely. After profiling with ProDelphi you know where the bottle neck is, not where it might be (see profiler types ).
