Watershed is a widespread technique for image segmentation. Many researchers apply the
method implemented in open source libraries without a deep understanding of its …

A centroidal Voronoi tessellation is a Voronoi tessellation whose generating points are the
centroids (centers of mass) of the corresponding Voronoi regions. We give some …

A hybrid multidimensional image segmentation algorithm is proposed, which combines
edge and region-based techniques through the morphological algorithm of watersheds. An …

Many classes of images contain some spatial regions which are more important than other
regions. Compression methods which are capable of delivering higher reconstruction quality …

An edge detection algorithm for digital images is proposed in this paper. Edge detection is
one of the important and most difficult tasks in image processing and analysis. In images …

In image compression technologies, fractal image compression/decompression has the
advantages of a high compression ratio and a low loss ratio. However, it requires a great …

In this paper, we propose a modified watershed algorithm for image segmentation using
distances transform and image smoothing method, an improved version of watershed …

This paper presents a new fast method for region merging after watershed segmentation.
We name it watershed collapsing algorithm (WCA) as its merging operation mimics the …

In this chapter, we introduce some recently developed fuzzy based techniques for image
segmentation. They are fuzzy thresholding, fuzzy rule-based inferencing scheme, fuzzy c …

Image compression is a means to perform transmission or storage of visual data in the most
economical way. Though many algorithms have been reported, research is still needed to …
