This paper presents an algorithm for segmenting 3D point clouds. It extends terrain elevation models by incorporating two types of representations: (1) ground representations based on averaging the height in the point cloud, (2) object models based on a voxelisation of the point cloud. The approach is deployed on Riegl data (dense 3D laser data) acquired in a campus type of environment and compared...
We present a study of the spatial variation of nuclear morphology of stromal and cancer-associated fibroblasts in the mouse mammary gland. The work is part of a framework being developed for the analysis of the tumor microenvironment in breast cancer. Recent research has uncovered the role of stromal cells in promoting tumor growth and progression. In specific, studies have indicated that stromal...
In Today's modern era Safer Navigation has become a major issue since most of our overseas logistics depends on floating vessels. In this paper an algorithm has been developed to classify the ships according to there dimension by using image processing. The image of the ship has been recorded by a stationary camera. We extract and calculate the dimension and parameters of the ship by using categories;...
We present an approach for synthesizing biological tissue textures from existing tissue samples. At microscopic resolution, tissues are characterized by a spatial arrangement of nuclei, cytoplasm, red-blood cells (RBCs) and adipose components etc. We employ 2-point correlation functions (2-pcfs) to encode the geometrical aspects of component arrangements in the synthesis process. The 2-pcfs belong...
This paper presents a SVM based computer-aided diagnosis (CAD) system for the characterization of clustered microcalcifications in digitized mammograms. First, the region of interest (ROI) in mammogram is enhanced using morphological enhancement (MORPHEN) method. Second, pixels in potential microcalcification regions are segmented out by using edge detection and morphological operations. Third, features...
