Recent work on the problem of Image Quality Assessment (IQA) has produced accurate subjective quality evaluators for visible light images. Two such algorithms are the Blind/Referenceless Image Spatial QUality Evaluator (BRISQUE) and the Natural Image Quality Evaluator (NIQE). Both models are useful in that they correlate highly with human visual perception of image quality. Given that other kinds...
We explore the use of Distributed Ray Tracing (DRT), an anti-aliasing technique from computer graphics, in multi-view computational stereo. As an example, we study ABM, a multi-view stereo algorithm based on a set of Hough transform accumulation operations. Augmenting ABM with DRT improves both internal signal quality and reconstruction accuracy. Results are given for both fundamental and complex...
Natural scene statistics (NSS) are an active area of research. Although there exist elegant models for NSS, the statistics of natural image distortions have received little attention. In this paper we study distorted image statistics (DIS) for natural scenes. We demonstrate that each distortion affects the statistics of natural images in a characteristic way and it is possible to parameterize this...
