Microaneurysms are the first clinical sign of diabetic retinopathy for automatic screening. The number of microaneurysms are used to indicate the severity of the disease. Early microaneurysm detection can help to reduce the occurrence of blindness. Mathematical morphology provides a systematic approach to analyze the geometric Characteristics of images and(More)
The effective recovery of the 3D structure of a scene using two or more 2D images of the scene, each acquired from a different viewpoint is a challenging task of stereovision. Defining pixel correspondence in stereo pairs is a fundamental process for automated image based effective 3D reconstruction. This paper presents modified Census based approach for(More)
The segmentation of organs in CT volumes is a prerequisite for diagnosis and treatment planning. In this paper, we focus on liver segmentation from contrast-enhanced abdominal CT volumes, a challenging task due to intensity overlapping, blurred edges, large variability in liver shape, and complex background with cluttered features. The algorithm integrates(More)
