A blob counter library written in pure javascript.

This library helps you find blobs in an image . Inspired by BlobCounter Class in AForge.NET Framework .

Installation

Just include the blobcounter.js anywhere you like :

<script type="text/javascript" src="blobcounter.js"></script>

Or the blobcounter.min.jswhich is minified :

<script type="text/javascript" src="blobcounter.min.js"></script>

Usage

NOTE: Input image must be black and white. ( black blobs with white background )

var blobs = new blobcounter(canvas); // Don't forget that input image must be all black and white ( black blobs with white background ) . Apply threshold filter to do that . 
var res = blobs.detect(1); // Radius area is one pixel . You can change it.

for (var i = 0; i < res.length; i++) {
	var cog = res[i].cog; // Center of gravity . res[i].cog.x and res[i].cog.y
	var mess = res[i].mess; // Number of pixels
}

See the example.html for a practical example .
