This paper addresses digital techniques used to automatically correct those color photographs whose range of trans-mittance densities is too large for visually acceptable image reproduction. The rst step consists in calibrating the image acquisition devices, and results are shown for two diierent models. Then, we present a method inspired by photographic techniques that uses modiied binary mask...

With the development of computer graphic techniques and smaller visual difference between photographic images (PG) and computer graphics (CG), splicing of computer graphics and photographic is becoming more common, which causes the need for automatically distinguishing computer generated images from real photographs. Based on several visual features that derived from color, texture and shape fe...

The unique results produced by simple studies of the Shroud of Turin sets this particular artifact apart from all other known artifacts. When photographed, the Shroud image appears more clearly to the human eye in the photographic negative than in the photopositive. When image-processed by a VP-8 Image Analyzer, the Shroud image produces a three-dimensional response unlike any other image so pr...

Feasibility of speckle tracking in optical coherence tomography (OCT) based on digital image correlation (DIC) is discussed in the context of elastography problems. Specifics of applying DIC methods to OCT, compared to processing of photographic images in mechanical engineering applications, are emphasized and main complications are pointed out. Analytical arguments are augmented by accurate nu...

The subject of the study is analysis preservation and creation an image in art photography. invention photography a technical considered second turning point human culture. An imagination, illusion, it reflection sensory world. object specificity evolution attitudes towards concept as aesthetic phenomenon. language fine art, earlier phenomenon, had significant impact on photographic image, but ...

one of the problems in the ground-based circular synthetic aperture radar is the dependence of the azimuth resolution to the antenna rotation radius and operational limitation of increasing it. to enhance the image quality in azimuth, model-based image formation through three methods: matched filter, inverse filter and optimum filter is suggested and analyzed. for the purpose of comparison, thr...

A photographic dataset is collected for testing image processing algorithms.
