Manual region-of-interest (ROI) definition is the conventional basis for calculating regional receptor binding potential (BP) values in neuroreceptor PET studies. In this study, we propose a fully automatic method to extract the left and right caudate and putamen in [C]raclopride BP images. The automatic extraction of these brain structures is challenging due to the small size of the structures...

Return on Investment (ROI) is one of the most popular performance measurement and evaluation metrics. ROI analysis (when applied correctly) is a powerful tool in comparing solutions and making informed decisions on the acquisitions of information systems. The purpose of this study is to provide a systematic research of the accuracy of the ROI evaluations in the context of the information system...

This paper describes an Interactive Parameter Adaptation Tool (IPAT) for determining parameters to control texture based segmentation of Regions of Interest (ROI) on images. This tool enables non-image processing experts to interact with evolutionary algorithms to produce a set of ROI segmentation parameters that are capable of segmenting ROI in response to existing system constraints.

White Spot Disease (WSD) is well known as a widespread viral disease in shrimps from 1992. Many studies focused on morphological, histopathological and epidemiological characteristic and pathogenecity of the disease but less on the determination of the severity of WSD using the histopathological features in target tissues. A generalized scheme for assigning a numerical qualitative value to sev...
