Heuristic Evaluation of Picture Archiving and Communication Systems (PACS)
Introduction: Poor User Interface design can be one of the probable reasons of users’ error and reduced incentive in using health information systems such as PACS. Heuristic evaluation is one the methods for assuring the proper user interface design of health information systems such as PACS. Method: This study was a descriptive-analytic research conducted in 2019 through using Nielsen usabilit...

متن کاملMeasuring picture quality in compressed systems
A method of estimating the picture quality of an MPEG-2 bitstream without requiring reference to the source picture is presented. The method uses information readily available from the early stages of decoding the bitstream. It is therefore highly suited to applications in which it is required to monitor several video channels and provide an automatic warning of possible picture quality problem...
متن کاملPicture Quality Prediction in Image Processing
Interpolations are among the most important tools for image processing. However, whether they are used for image compression and reconstruction purposes or for the increase of the image resolution along vertical, horizontal or both dimensions, the induced interpolation errors are often only qualitatively and a posteriori described. In this paper, we propose to extend a method used in an OFDM co...
متن کاملBlue Sky Detection for Picture Quality Enhancement
Content analysis of video and still images is attractive for multiple reasons, such as enabling content-based actions and image manipulation. This paper presents a new algorithm and feature model for blue-sky detection. The algorithm classifies the sky areas by computing a pixel-accurate sky probability. Such a probabilistic measure matches well with the requirements of typical video enhancemen...
