Advance image classification system focuses on synthetic (e.g non-photographic) & Natural (e.g photographic) images. The classification of images based on semantic description is a challenging and important problem in automatic image identification. An algorithm for natural and synthetic image classification has been developed. Some features are extracted from the raw images data in order to ex...

A large scale psychophysical experiment was carried out to judge the perception of image quality of the photographic images. Two types of experiments, pair comparison and categorical judgment, were conducted for evaluating image difference and absolute quality respectively. Test images were generated by rendering the eight selected original images according to the change of lightness, chroma, c...

This paper describes a new image collection created for the CLEF (Cross Language Evaluation Forum) cross-language image retrieval (ImageCLEF) track. This royalty-free collection provides additional evaluation data for ImageCLEF, and in particular provides a new collection for the ad-hoc retrieval task over the existing St. Andrews historic photographic collection. This new image benchmark (refe...

Because various parts of an object are different distances from an observer, and light takes a finite time to reach the observer, the appearance of a relativistically moving object will be very different from that given by the Lorentz contraction. We derive equations that can be applied to a photographic image so that the Lorentz contraction can still be observed. We also give equations that qu...
