Daguerreotypes are sharply defined, highly reflective, one-of-a-kind photographs on silver-coated copper plates, packaged behind glass and kept in protective cases. Introduced in 1839 by Louis-Jacques-Mandé Daguerre, the daguerreotype process was the first commercially successful photographic process, and is distinguished by a remarkable clarity of pictorial detail. Daguerreotypes were popular ...

We propose a new algorithm to digitally restore vintage photographic prints affected by foxing and water blotches. It semiautomatically recovers the defects utilizing the features of the stains. The restoration process enhances the residual image information still present in the area. It is composed of three different steps: inpainting, additive-multiplicative (A-M) modeling, and interpolation....

In this paper , we describe a relational modeling technique which categorizes three-dimensional objects at a gross level. These models may then be used to classify and recognize two dimensional views of the object, in a scene analysis system.

Imperative visual data frequently vanishes when color applications are seen by partially color blind users. A new method for adaptive interface for accommodating color blind users is presented. The method presented here has two sections: 1) test client perceivability by utilizing Ishihara plates. 2) change the interface color scheme to accommodate color blind users if necessary. We demonstrate ...

Abstract The melting and recrystallization behavior of -iPP crystal induced by β -nucleating agent was studied. A new type α-modification has been developed self-seeding process. growth process these crystals is just like “photographic development process.” Crystalline phase transformation the memory effect caused local order observed during annealing high temperature sufficient to destroy β-nu...
