| Motion Detection Algorithm (36424 hits) |
| Posted by Prabu Arumugam on Apr-09-2013 |
| This article explains a simple motion-detection algorithm with full source code in C# and Silverlight. The algorithm is implemented by reading and manipulating the images pixel-by-pixel (no third party libraries are used). This is an ideal example for programmers who begin morphological image processing algorithms. |

| Finding all Subsets of a Set (80960 hits) |
| Posted by Prabu Arumugam on Jul-18-2010 |
| This article explains how to find all subsets of a given set of items, without using recursion. A set contains 2N subsets, where N is the number or count of items in the set. The subsets are found using binary patterns (decimal to binary) of all the numbers in between 0 and (2N - 1). |
