A Noise Tolerant Watershed Transformation with Viscous Force for Seeded Image Segmentation
The watershed transform was proposed as a novel method for image segmentation over 30 years ago. Today it is still used as an elementary step in many powerful segmentation procedures. The watershed transform constitutes one of the main concepts of mathematical morphology as an important region-based image segmentation approach. However, the original watershed transform is highly sensitive to no...
متن کاملRobust Watershed Segmentation Using the Wavelet Transform
The watershed transform has been used for image segmentation relying mostly on image gradients. However, background noise tends to produce spurious gradients, that cause over-segmentation and degrade the output of the watershed transform. Also, low-contrast edges produce gradients with small magnitudes, which may cause different regions to be erroneously merged. In this paper, a new technique i...
متن کاملObjects Counting Using Mark-Controlled Watershed Transform
This paper introduces the object counting using the mark controlled watershed transforms. Watershed transform is usually adopted for image segmentation in the area of image processing and image analysis because it always generates closed contours for each region in the original image. This method is good choice for image segmentation in the field of mathematical morphology. In this paper we are...
متن کاملMinimal Set of Markers for the Watershed Transform
This paper discusses the inverse problem of the watershed. From a partition obtained by the watershed from markers, find the minimal set of markers that reproduces the same watershed partition. We present a solution based on the minimum spanning tree and introduce the concept of marker receptive region. We also review the watershed transform based on the minimum spanning forest problem. Two app...
متن کاملThe Watershed Transform: Definitions, Algorithms and Parallelization Strategies
The watershed transform is the method of choice for image segmentation in the field of mathematical morphology. We present a critical review of several definitions of the watershed transform and the associated sequential algorithms, and discuss various issues which often cause confusion in the literature. The need to distinguish between definition, algorithm specification and algorithm implemen...
