The attached project performs simple blob detection in an image.

The sample image attached with the project contains discrete (distinct) blobs of different shapes and locations all against a plain white background.

The code loops for all pixels in the image and checks whether the pixel color is Black which indicates reaching a blob. When it does reach a blob, it uses the magic wand region selection function to select the blob and fill it with white to eliminate it. It then gives the region rectangle location and its center, and total count of the pixels (area) of the blob.

The project uses LEADTOOLS 18 .NET and C# VS 2010. To build it, extract the attached ZIP file into a folder directly inside the LEADTOOLS 18\Examples\DotNet\CS\ folder.

The attached C# project is updated to use the current version of LEADTOOLS, which is v20.
