The Mumford-Shah functional minimization, and related algorithms for image segmentation, involve a tradeoff between a twodimensional image structure and one-dimensional parametric curves (contours) th...
Integrated Active Contours for Texture Segmentation
Active contours without edges anisotropic diffusion Beltrami framework Gabor analysis geodesic active contours image manifolds texture segmentation
2010/1/7
We address the issue of textured image segmentation in the context of the Gabor feature space of images. Gabor filters tuned to a set of orientations, scales and frequencies are applied to
the images...
AUTOMATED CLASSIFICATION OF SUBCELLULAR PATTERNS IN MULTICELL IMAGES WITHOUT SEGMENTATION INTO SINGLE CELLS
AUTOMATED CLASSIFICATION OF SUBCELLULAR PATTERNS MULTICELL IMAGES
2009/12/23
Fluorescence microscope images capture information from
an entire field of view, which often comprises several cells
scattered on the slide. We have previously trained
classifiers to accurately pre...
Brain Structure Segmentation from MRI by Geometric Surface Flow
Brain Structure Segmentation MRI
2009/9/8
We present a method for semiautomatic segmentation of brain structures such as thalamus from MRI images based on the concept of geometric surface flow. Given an MRI image, the user can interactively i...
