Watershed Image Segmentation: Marker controlled flooding

The watershed transform is a computer vision algorithm that serves for image segmentation. This method can extract image objects and separate foreground from background. This tutorial shows how can implement Watershed transformation via Meyer’s flooding algorithm.


Skin Detection and Segmentation in RGB Images

The Skin Detection and Segmentation is a process of finding skin-colored image regions from video frames or still pictures. Typically  this is a pre-processing step in the digital image analysis to find significant regions such as body, hands, faces, etc.

Hough Transform – Basic Shape Detection

The Hough Transform is a method to find shapes in an image. The classical transformation is initially designed to identify lines in the image. Later the transform extends to identify different kind of shapes such as circles, ellipses and even arbitrary objects.
