چکیده
He has published over 70 papers in journals and international conferences on photo-realistic graphics. He is currently vice chair of ACM SIG-GRAPH. His research is investigating the use of photo-realistic graphics in the visu-alisation of archaeological site reconstructions and techniques which may be used to reduced computation times without affecting the perceptual quality of the images. Scott Daly has degrees in electrical engineering and bioengineering, with a thesis directed toward retinal neurophysiology. He has worked for RCA, Photo Electronics Corporation, and Eastman Kodak in digital video, laser scanning, image compression, image fidelity models, and data image embedding. He shares an Emmy with Kodak colleagues for a video transceiver used in the 1989 Tianamen Square news coverage. Conference activities include papers, tutorials, and chairing sessions for SPIE, SPSE and RIDT. Currently at Sharp Laboratories of America, he is now applying visual models towards improving digital video and displays. He has 12 patents ranging from tonescales to steganography. Ann McNamara is a research member of the Vision and Graphics Laboratory at the University of Bristol, where she works on image evaluation and comparison using data collected from psychophysical experiments. Her area of interest mainly focuses on evaluating the fidelity of computer imagery to real scenes, with an emphasis on human observer evaluation. She has published a number of papers outlining these results Dr Karol Myszkowski is currently a visiting senior researcher at the Max-Planck-Before he joined academia he worked for computer graphics industry developing global illumination and rendering software. His current research is investigating the role of human perception to improving the performance of photo-realistic rendering and animation techniques. Bristol. He has a background in vision science, and his current research is investigating the way in which human vision samples the natural visual environment, especially on the role of colour information in such environments.

A Robust SAR NLFM Waveform Selection Based on the Total Quality Assessment Techniques
Design, simulation and optimal selection of cosine-linear frequency modulation waveform (CNLFM) based on correlated ambiguity function (AF) method for the purpose of Synthetic Aperture Radar (SAR) is done in this article. The selected optimum CNLFM waveform in contribution with other waveforms are applied directly into a SAR image formation algorithm (IFA) and their quality effects performance ...
متن کاملA Novel Image Structural Similarity Index Considering Image Content Detectability Using Maximally Stable Extremal Region Descriptor
The image content detectability and image structure preservation are closely related concepts with undeniable role in image quality assessment. However, the most attention of image quality studies has been paid to image structure evaluation, few of them focused on image content detectability. Examining the image structure was firstly introduced and assessed in Structural SIMilarity (SSIM) measu...
متن کاملImproving the quality of images synthesized by discrete cosines transform – regression based method using principle component analysis
Purpose: Different views of an individuals’ image may be required for proper face recognition. Recently, discrete cosines transform (DCT) based method has been used to synthesize virtual views of an image using only one frontal image. In this work the performance of two different algorithms was examined to produce virtual views of one frontal image. Materials and Methods: Two new meth...
متن کاملImage quality metrics for the evaluation of print quality
Image quality metrics have become more and more popular in the image processing community. However, so far, no one has been able to define an image quality metric well correlated with the percept for overall image quality. One of the causes is that image quality is multi-dimensional and complex. One approach to bridge the gap between perceived and calculated image quality is to reduce the compl...
متن کاملObjective Image Quality Assessment of Color Prints
Measuring the perceived quality of printed images are important to assess the performance of printers and to evaluate technology advancements. Image quality metrics have been proposed to objectively assess the quality of images, and new metrics are continuously proposed. However, applying these metrics to printed images are not straightforward, since they require a digital input. We present a n...
