Description

cvBlob is a library for computer vision to detect connected regions in binary digital images. cvBlob performs connected component analysis (also known as labeling) and features extraction.

Features

• Binary image labeling.
• Features extraction and render: blob orientation, centroid, contours, color,...
• Contours functions.
• Basic blob tracking.
• Interface similar to OpenCV.

News

• 04/01/2011: Version 0.10.3 released: cvSaveImageBlob function, bugs fixed, compilation and installation improved. Also, a great contribution of Giandomenico De Sanctis: a DLL to use cvLabel from others language (Delphi, for example).
• 24/09/2010: Version 0.10.2 released: new functions and bugs fixed.
• 27/05/2010: Version 0.10.1 released: New function cvWriteContourPolygonCSV. Memory-leaks fixed.
• 13/04/2010: Version 0.10.0 released!!! New labeling algorithm, more than twice faster. Internal contours. Blob color mean. And something more...
