The research in this article aims to provide an overview of how to calculate the ROI for E-commerce applications so that this information, and the attached ROI Calculator Tool Template, can be used by organizations to reduce the time in preparing the ROI for a project. Although there is much written about ROI, there is not that much said about how to prepare one specifically for an E-commerce p...

Region Of Interest (ROI) coding is one of the innovative functionalities supported by JPEG 2000, the new ISO/ITU-T still image coding standard developed by the Joint Photographic Experts Group (JPEG). It enables a non-uniform distribution of the image quality between a selected region (the ROI) and the rest of the image (background). This feature is obtained by scaling background coefficients i...

One of the significant contributors to the variation of H/ M ratio in cardiac imaging, are the settings of the regions of interest (ROIs) that are used. Currently, as correctly described by Chen et al. [1, 2], there are three main approaches ROI is placed along the anterior part of the LV wall [2]. In our current ongoing study in pediatric patients by van der Palen et al.., we compared both app...

BACKGROUND AND PURPOSE This study aimed to examine the temporal relationship between tissue perfusion and apparent diffusion coefficient (ADC) changes within 6 hours of ischemic stroke onset and how different reperfusion patterns may affect tissue outcome in ADC lesions. METHODS Thirty-one participants were sequentially imaged at 3 hours, 6 hours, and 1 month post-stroke. Three regions of int...

This paper describes the functionality in the JPEG 2000 Part 1 standard, for encoding images with predefined regions of interest (ROI) of arbitrary shape. The method described is called the Maxshift method. This method is based on scaling of the wavelet coefficients after the wavelet transformation and quantization. By sufficiently scaling the wavelet coefficients used to reconstruct the ROI, a...

Introduction: The limited resolution of the imaging system causes partial volume effects (PVEs). These results in spreading of image counts to the neighboring pixels. This phenomenon is called spill-out effect. This study aimed at quantifying PVEs using ImageJ. Methods:Technetium-99m solution of concentration of 74 kBq/ml was filled into spheres A, B<...

We present a simple and ef£cient scheme for protecting a region of interest (ROI) in an image sent across lossy communication networks. To increase the probability that the ROI is received with high quality, we extend the unequal loss protection framework of MD-SPIHT [1] by adding more redundancy to the ROI than to other parts of the image. The ROI is therefore heavily protected at the expense ...

INTRODUCTION Male live births occur slightly in excess of female births. The ratio of male divided by total births is referred to as M/F. Many factors reduce M/F including toxins, stress, and privation, with excess male foetal loss. "The Troubles" (1969-1998) of Northern Ireland (NI) and the economic downturn of Republic of Ireland (ROI) from 2007 posed stresses with corresponding controls. Thi...

Regions Of Interest (ROI) image coding is one of the most significant features in JPEG2000. It allows ROIs of the image are of higher importance than background (BG). In this paper, a new and efficient scalingbased method so-called Partial Bitplane Alternating Shift (PBAShift) is described. The new algorithm firstly shifts up partial most significant bitplanes of ROI. Then, the most significant...

The objective of this paper is to develop different method for image compression without reducing the resolution for Region of Interest in the images. Mostly medical images for diagnosis purpose have some specific region; this region is known as Region of Interest (ROI). Here we separate our ROI from background and then apply Feed Forward Neural Network (FFN) compression to ROI and background i...
