Live-wire method with wavelet cost map definition for mri images

There are edge based segmentation approaches among the set of methods utilized to image segmentation. This type of methods analyse image gradient features (like the first, the second derivative or them modification). Perfect tool to image processing is wavelet transformation which enables edges detection and often gets better results. In this paper wavelet transformation advantages was utilized. This tool was used to cost map definition. Cost map is a matrix which informs how many features of boundary each pixel possess. Then this cost map definition was applied to live-wire method. The method is semi-automatic and requires user interaction rely on points specification.
