This paper describes a study conducted to understand, in part, the effects of web interface features (image size, fidelity, and motion) on responses such as attention, and memory. The increasing proliferation of B2C web sites and their attempts to enhance the experience of customers shopping on-line has made the work of Reeves and Nass (1996) on the psychological responses elicited by interacti...

Measurement of visual quality is crucial for many image and video processing applications. Traditionally, quality assessment (QA) algorithms predict visual quality by comparing a distorted signal against a reference, typically by modeling the Human Visual System (HVS). In this paper, we adopt a new paradigm for video quality assessment that is an extension of our previous work on still image QA...

micropropagated plantlets derived from three different grape rootstock genotypes namely, dogridge (vitis champini), so4 (v. berlandieri×v. rupestris) and ari-h-144 (v. vinifera×v. labrusca) were subjected to randomly amplified polymorphic dna (rapd) and inter simple sequence repeats (issr) analyses in order to evaluate their genetic stability and/or detect likely existing variations among in vi...

This paper studies the model of minimizing total variation with an L-norm fidelity term for decomposing a real image into the sum of cartoon and texture. This model is also analyzed and shown to be able to select features of an image according to their scales.

ÐWe propose a novel method for object tracking using prototype-based deformable template models. To track an object in an image sequence, we use a criterion which combines two terms: the frame-to-frame deviations of the object shape and the fidelity of the modeled shape to the input image. The deformable template model utilizes the prior shape information which is extracted from the previous fr...

Balancing the trade off between the spatial and temporal quality of interactive computer graphics imagery is one of the fundamental design challenges in the construction of rendering systems. Inexpensive interactive rendering hardware may deliver a high level of temporal performance if the level of spatial image quality is sufficiently constrained. In these cases, the spatial fidelity level is ...

Due to the much larger luminance and contrast characteristics of high dynamic range (HDR) images, wellknown objective quality metrics, widely used for the assessment of low dynamic range (LDR) content, cannot be directly applied to HDR images in order to predict their perceptual fidelity. To overcome this limitation, advanced fidelity metrics, such as the HDR-VDP, have been proposed to accurate...
