Region of interest (ROI) coding is one of the innovative functionalities supported by JPEG2000. It enables a non-uniform distribution of the available bit budget (i.e. image quality) between a selected region (ROI) and the rest of the image (background). This is achieved by appropriate scaling of the background wavelet coefficients. Two different methods are used for ROI coding, the MAXSHIFT me...

Background: Despite the existence of various imaging methods, the accurate diagnosis of many neurodegenerative diseases is still controversial. The use of advanced imaging techniques, such as the diffusion weighted imaging can be help the early detection of MS and evaluation of the treatment efficacy in these patients. Materials and method: 24 MS patients with acute attack and thirty healthy s...

Objective: Although, earlier studies have evaluated the significance of various estradiol patterns during controlled ovarian hyperstimulation (COH), their prognostic significance remains unclear. The objective of this study is to investigate the rate of increase in estradiol (ROI-E2) during COH and evaluate it as a predictor of ovarian response. Materials and Methods: In this retrospective stud...

This supplementary file presents new methods to analyze PC-MR velocity data using the principles of control volume analysis. PC-MR phase and magnitude images were imported into MATLAB for image processing. Spatiotemporal velocity values were derived from the phase images as follows. A static background region was manually selected to determine the phase value corresponding to zero velocity, com...

Abstract The Republic of Ireland (ROI) currently reports the highest incidence rates Shiga-toxin producing Escherichia coli (STEC) enteritis and cryptosporidiosis in Europe, with spatial distribution both infections exhibiting a clear urban/rural divide. To date, no investigation role socio-demographic profile on either infection ROI has been undertaken. current study employed bivariate analyse...

Hand tracking is one of the essential elements in vision based hand gesture recognition system. The tracked hand image can provide a meaningful gesture for more natural ways of Human Computer Interaction (HCI) systems. In this paper, we present a fast hand tracking method based on the fusion of skin and motion features incorporated covariance matrix. First, hand region is detected using a fusio...

Region Of Interest (ROI) coding is a prominent feature of some image coding systems aimed to prioritize specific areas of the image through the construction of a codestream that, decoded at increasing bit-rates, recovers the ROI first and with higher quality than the rest of the image. JPEG2000 is a wavelet-based coding system that is supported in the Digital Imaging and Communications in Medic...
