An Approach towards Edge Detection and Watershed Segmentation Based on an Interval-Valued Morphological Gradient

چکیده
The appropriate mathematical framework of mathematical morphology (MM) is given by complete lattices. Recently, the observation that the class of intervalvalued fuzzy sets constitutes a complete lattice has given rise to an extension of fuzzy MM (FMM) called interval-valued fuzzy mathematical morphology. In contrast to FMM, interval-valued FMM allows us to model uncertainty in the pixel values of a gray-scale image. We have already applied this idea to develop an interval-valued edge detector. In this context, the uncertainty was due to image capture. In the applications concerning edge detection and segmentation presented in this paper, another type of uncertainty emerges from different results produced by three well-known tomographic image recon-

Improving edge detection and watershed segmentation with anisotropic diffusion and morphological levellings
Edge preserving smoothing and image simplification is of fundamental importance in a variety of remote sensing applications during feature extraction and object detection procedures. The construction of a pre-processing filtering tool for edge detection and segmentation tasks is still an open matter. Towards this end, this paper brings together two advanced nonlinear scale space representations...
متن کاملA Color Preserving Image Segmentation Method
In this work a color based, edge-region cooperative segmentation technique is presented. The segmentation process consists of two basic stages. In the first stage a novel fast vector edge detector based on the image density map is used, to solve the multidimensional boundary estimation problem. The watershed transform with some form of morphological prefiltering, is applied on the edge image to...
متن کاملTem Images of Membranes: a Multiresolution Edge-detection Approach for Watershed Segmentation
This paper presents a method for the segmentation of membrane images acquired with transmission electron microscopes (TEM) for classification purposes. It relies on a multiresolution representation of the image to detect the edges at appropriate scales by an adaptive thresholding of the gradient images. The edges found at the different scales are combined and homogeneous regions are extracted w...
متن کاملVideo Object Segmentation Using Spatio-Temporal Information and Marked-Watershed Operation
In this paper, we propose a video object segmentation algorithm based on spatio-temporal information and marked-watershed for extracting the moving objects from a video sequence. The algorithm begins with difference image between two adjacent frames and, using the Canny operator on the difference image, determines the initial edge mask for the object in motion. Morphological techniques are appl...
متن کاملAutomatic segmentation of granular objects in images: Combining local density clustering and gradient-barrier watershed
Blob or granular object recognition is an image processing task with a rich application background, ranging from cell/nuclei segmentation in biology to nanoparticle recognition in physics. In this study, we establish a new and comprehensive framework for granular object recognition. Local density clustering and connected component analysis constitute the first stage. To separate overlapping obj...
