Image fusion is the process by which input images are fused in order to increase the quality. The input images must be the images of the same scene with different quality measures. The quality of the output image will be better than any of the input images. The main methods of the image fusion involve simple image fusion, pyramid based image fusion and wavelet based image fusion. Image fusion m...

No-reference image quality assessment aims to predict the visual quality of distorted images without examining the original image as a reference. Most no-reference image quality metrics which have been already proposed are designed for one or a set of predefined specific distortion types and are unlikely to generalize for evaluating images degraded with other types of distortion. There is a str...

Traditional visual quality metrics measure fidelity instead of quality, even though fidelity, i.e. the accuracy of the reproduction of the original on the display, is just one of the many factors determining the overall perceived quality. In this paper, the addition of image appeal attributes is investigated in order to bridge this gap. Sharpness and colorfulness are identified among these attr...

In industry it is not well realised that a service centre is potentially one of the major contributors to quality improvement. Service is able to collect vital information about the "eld behaviour of products in interaction with customers. If this information is well analysed and communicated, the recurrence of old problems in new products will drastically be reduced and so will the expenses on...

A new integrated image analysis package with quantitative quality control schemes is described for cDNA microarray technology. The package employs an iterative algorithm that utilizes both intensity characteristics and spatial information of the spots on a microarray image for signal-background segmentation and defines five quality scores for each spot to record irregularities in spot intensity...

Extracting meaningful information out of vast amounts of high-dimensional data is challenging. Prior research studies have been trying to solve these problems through either automatic data analysis or interactive visualization approaches. Our grand goal is to derive representative and generalizable quality metrics and to apply these to amplify interesting patterns as well as to mute the uninter...

Guaranteeing a certain level of quality for multimedia streaming applications is quite well understood in terms of network QoS, but it is much more tenuous in terms of perceptual quality as perceived by the user. In this paper, we classify video quality measurement schemes and review existing approaches with a focus on non-intrusive quality metrics, which do not require access to the reference ...

DESYNC-TDMA is a representative bio-inspired MAC protocol which assigns slots of each node evenly in decentralized manner. However, it could suffer from bottleneck node on the delivery path because the slot is evenly assigned according to the number of neighbors in two hop range. In such a case the routing path having smaller slot length could be chosen due to its shorter hop count. This proble...
