Open Source Software (OSS) projects have the unique opportunity to reach an unprecedented level of software quality by tapping into its community and collaborative power. However, the community process of collaborative software Quality Assessment (QA) may not reach its full potential or worse be easily jeopardised by malevolent entities because there is a lack of protection mechanisms, easy-to-...

Digital video data, stored in video databases and distributed through communication networks, is subject to various kinds of distortions during acquisition, compression, processing, transmission, and reproduction. For example, lossy video compression techniques, which are almost always used to reduce the bandwidth needed to store or transmit video data, may degrade the quality during the quanti...

During spermatogenesis, spermatozoa lose many of the organelles that most somatic cells possess (such as endoplasmic reticulum, lysosomes, and most of the cytoplasm) reducing the “baggage” they need to carry en route to the oocyte. The primary function of a spermatozoon, fertilizing an oocyte, is an integrated set of processes, which require multiple cell attributes. Therefore, although the spe...

The success of systems making use of ontology schemas depend mainly on the quality of their underlying ontologies. This has been acknowledged by researchers who responded by suggesting metrics to measure different aspects of quality. Tools have also been designed, but determining the set of quality metrics to use may not be a straightforward task. Research on ontology quality shows that detecti...

Image quality assessment is a difficult problem in the field of image processing without any acceptable solution yet. Quality assessment of textures, which is the topic of this work, is even harder problem. This work presents an overview and a description of current state of the art methods as well as brief experiments on textures and a discussion about the usability of these methods on textures.

MITRE’s Architecture Quality Assessment (AQA) is intended to provide an objective and repeatable technique for the evaluation of system architectures. This paper describes the scope of AQA and its intended use; the evaluation methodology embodied in the AQA; the process of conducting an architecture assessment using the AQA; the current status of the AQA; and a comparison with other approaches ...

Most image and video compression algorithms that have been proposed to improve picture quality relative to compression efficiency have either been designed based on objective criteria such as signal-to-noise-ratio (SNR) or have been evaluated, post-design, against competing methods using an objective sample measure. However, existing quantitative design criteria and numerical measurements of im...

the video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. the objective of this study is to assess the video quality using image features extraction without using reference video. rmse values and processing ...

development of ultrasound technique has not been progressing for evaluating the internal quality of fruits as fast as that of processed foods. in this research for quality assessment of pear fruit (shah miveh variety) an ultrasonic measurement system was constructed to transmit and receive the ultrasonic waves. the apparatus included a pulser-receiver, a pair of 75 khz ultrasonic transducers wi...
