A 2-D acoustooptic spectrum analyzer with the associated reference function generator and real-time image processor has been constructed. The operation of the analyzer and the experimental considerations for obtaining a high resolution spectrum in real time are described.

This paper gives details of the image quality analysis of ASAR alternating polarisation mode APP and APM products performed during the ASAR validation phase. Initially, a description of the analysis methodology and performance assessment tools, image properties and example APP and APM products is given followed by the image quality analysis. This analysis includes format verification, visual in...

A growing number of tools now allow live recordings of various signaling pathways and protein-protein interaction dynamics in time and space by ratiometric measurements, such as Bioluminescence Resonance Energy Transfer (BRET) Imaging. Accurate and reproducible analysis of ratiometric measurements has thus become mandatory to interpret quantitative imaging. In order to fulfill this necessity, w...

We developed a software system consisting of a container app for smartphones and a web portal. The container app, named “MimasAR” (iOS container app: https://itunes.apple.com/sg/app/mimasar/id988692600?mt=8; Android container app: https://play.google.com/store/apps/details?id=sg.edu.astar.i2r.mimasar&hl=en) can be used to recognize Chinese characters on printed media quickly and reliably for in...

We present a practical application of polymerase chain reaction single-strand conformational polymorphism (PCR-SSCP) using a fluorescence-based image analyzer. Fluorescence-labeled primers were used to amplify target sequences. After nondenaturing polyacrylamide gel electrophoresis using a conventional sequencing gel apparatus, the glass plate was directly transferred from the gel box to the im...

An important aim of research on the blind image quality assessment (IQA) problem is to devise perceptual models that can predict the quality of distorted images with as little prior knowledge of the images or their distortions as possible. Current state-of-the-art ‘general purpose’ no reference (NR) IQA algorithms require knowledge about anticipated distortions in the form of training examples ...

Context: Mobile applications support a set of user-interaction features that are independent of the application logic. Rotating the device, scrolling, or zooming are examples of such features. Some bugs in mobile applications can be attributed to user-interaction features. Objective: This paper proposes and evaluates a bug analyzer based on userinteraction features that uses digital image proce...

SUMMARY Ka-me is a Voronoi image analyzer that allows users to analyze any image with a convex polygonal tessellation or any spatial point distribution by fitting Voronoi polygons and their dual, Delaunay triangulations, to the pattern. The analytical tools include a variety of graph theoretic and geometric tools that summarize the distribution of the numbers of edges per face, areas, perimeter...
