Atherosclerosis is a condition where the arteries become narrowed and hardened because of excessive build up of fatty substances called plaques around the artery wall. The disease disrupts the flow of blood around the body resulting in serious cardiovascular complications. The Intima Media thickness (IMT) is used as a validated measure for the evaluation of atherosclerosis. Manual assessment of...

This review will discuss the use of manual grading scales, digital photography, and automated image analysis in the quantification of fundus changes caused by age-related macular disease. Digital imaging permits processing of images for enhancement, comparison, and feature quantification, and these techniques have been investigated for automated drusen analysis. The accuracy of automated analys...

Careful evaluation of Optic nerve head structure and its documentation is extremely important for diagnosis of Glaucoma, an eye disease which leads to vision loss. This work focuses on automatic segmentation of Optic disc from fundus images, which is an important parameter for disease diagnosis. We investigate and compare performance of five methods used for Optic disc segmentation. These five ...

Inconsistency and a lack of reproducibility are commonly associated with semi-automated segmentation methods. In this study, we developed an ensemble approach to improve reproducibility and applied it to glioblastoma multiforme (GBM) brain tumor segmentation on T1-weigted contrast enhanced MR volumes. The proposed approach combines samplingbased simulations and ensemble segmentation into a sing...

Tuberculosis (TB) is an important public health issue in this world. In 1992, World Health Organization (WHO) has determined tuberculosis as Global Emergency. The cause of tuberculosis disease is Mycobacterium tuberculosis. This bacteria is bar shaped and has the quality of acid fast so that it’s also known as Acid Fast Bacilli (AFB). In this research, an algorithm to identifying and counting t...

In this paper, a computer vision based system is introduced to automatically grade apple fruits. Segmentation of defected skin is done by three global thresholding techniques (Otsu, isodata and entropy). Stem−end/calyx regions falsely classified as defect are removed. Segmentations were visually best with isodata technique applied on 750nm filter image. Statistical features are extracted from t...

Methods CMR imaging at 3T (Bio-graph mMR, Siemens Healthcare, Erlangen, Germany) was performed in 18 STEMI patients within 10 days of PPCI using T2-mapping and T1-mapping by MOLLI (WIP #699; Siemens Healthcare; UK). Matched short-axis T1 and T2 maps covering the entire left ventricle were analyzed by 2 experienced investigators using 3 analytical methods (in-house macro, ImageJ): manual segment...

Glaucoma is an eye disease that can lead to permanent blindness caused by increased Intraocular Pressure (IOP). There are several methods detect glaucoma, namely Optical Nerve Hypoplasia Stereo Photographs (ONHSPs), Coherence Tomography (OCT), Scanning Laser Polarimetry (SLP), and Confocal Ophthalmoscopy (CSLO). However, these require a lot of money expert supervision. In this paper, glaucoma c...

otherwise it is segmented into another class. Multi-class thresholding is defined in a similar manner. There exist various algorithms for the determination of the thresholding value [2-4]. ABSTRACT: An iterative image segmentation algorithm that segments an image on a pixel-by-pixel basis is described. The observation information to be utilized is the joint gray level values of the pixel to be ...
