A combination of K-means, watershed segmentation method, and Difference In Strength (DIS) map was used to perform image segmentation and edge detection tasks. We obtained an initial segmentation based on K-means clustering technique. Starting from this, we used two techniques; the first is watershed technique with new merging procedures based on mean intensity value to segment the image regions...

The watershed transform is a well-known approach for image segmentation. Watershed from markers and hierarchical watershed are derived from the watershed transform and are suitable for interactive image segmentation: in the former, the user can edit markers and control the segmentation result; in the latter, the user can select an image partition from a nested set of partitions. We investigate ...

This paper deals with region based watershed segmentation for developing “MemberingFilters”.Watershed transformation is a common technique for image segmentation. Region based segmentation classify a particular image into a number of regions or classes. Region-based segmentation methods attempt to partition or group regions according to Intensity values from original images, Textures or pattern...

Introduction: Lung cancer is one of the most common causes of cancer-related deaths worldwide. Nowadays PET/CT plays an essential role in radiotherapy planning specially for lung tumors as it provides anatomical and functional information simultaneously that is effective in accurate tumor delineation. The optimal segmentation method has not been introduced yet, however several ...

shape and movement features of sperms are important parameters for infertility study and treatment. in this article, a new method is introduced for characterizing sperms in microscopic videos. in this method, first a hypothesis framework is defined to distinguish sperms from other particles in captured video. then decision about each hypothesis is done in following steps: selecting some primary...

Breast tumor segmentation is needed for monitoring and quantifying breast cancer. However, automated tumor segmentation in mammograms poses many challenges with regard to characteristics of an image. A comparison of two different semi-automated methods, viz., modified gradient magnitude region growing technique (MGMRGT) and watershed method is undertaken here for evaluating their relative perfo...

Abstract. The watershed transform and the morphological reconstruction are two of the most important operators for image segmentation in the framework of mathematical morphology. In many situations, the segmentation requires the classical watershed transform of a reconstructed image. In this paper, we introduce the IFT-watershed from gray scale marker a method to compute at same time, the recon...

Automatic target recognition is a challenging task with a wide variety of potential applications in the industrial, military and medical fields. Region segmentation is a crucial step towards automatic segmentation of images. Under some severe conditions of improper illumination and unexpected disturbances, the blurring images make it more difficult for target recognition, which results in the n...
