Given a grayscale photograph as input, this paper attacks the problem of hallucinating a plausible color version of the photograph. This problem is clearly underconstrained, so previous approaches have either relied on significant user interaction or resulted in desaturated colorizations. We propose a fully automatic approach that produces vibrant and realistic colorizations. We embrace the und...

We present a system for automatically generating custom, structured image-maps for input depth-maps. Our system thus allows quick fitting of masses of objects with tailor-made image-maps. Given a depth-map of a novel 3D object, our method tiles it with intensities from similar, pre-collected, textured objects. These are seamlessly merged to form the new image-map. This process is performed by o...

Photocatalysis has attracted significant attention as a potential issue for the degradation of toxic organic pollutants such as Congo Red. In this research spherical Pure ZnO nano particles and Ni-Co-ZnO nano composites (Zn0.95Ni0.04Co0.01O,  Zn0.95Ni0.025Co0.025O and  Zn0.95Ni0.01Co0.04O) have been synthesized by precipitation method. X- ray diffraction, Fourier transform Infra Red ,field emis...

Colorization in X-ray material discrimination is considered one of the main phases baggage inspection systems for detecting contraband and hazardous materials by displaying different with specific colors. The substructure identifies based on their atomic number. However, images are checked assigned a human factor, which may decelerate verification process. Therefore, researchers used computer v...

DE protection, demineralization, de colorization, and acetylation. Protein accesses were used to obtain chitosan from shrimp shell waste. Using FTIR, SEM XRD. It was characterized. Also analyzed the physiochemical parameter such as moisture content, hydrogen meter, viscosity, degree of acetylation solubility The age bacterial culture influenced its susceptibility with cells being most prone in ...

Image Colorization is the problem of defining colors for grayscale images. Recently many research works have been conducted to propose fully-automatic colorization methods. However, these papers failed in colorizing images with multiple objects accurately. This might be because dealing whole multi-object image as a single input. Following efforts made last few years, this paper aims at studying...

Region-based approaches have been proposed to computerassisted colorization problem, typically using shape similarity and topology relations between regions. Given a colored frame, the objective is to automatically colorize consecutive frames, minimizing the user effort to colorize the remaining regions. We propose a new colorization algorithm based on graph matching, using Belief Propagation t...

This paper presents a novel approach to grayscale image matting and colorization. The first part of this approach is an efficient grayscale image matting algorithm in Bayesian framework. The foreground and background color distributions, and the alpha’s distribution are modelled with spatially varying sets of Gaussians. The major novelties of this matting algorithm are the introduction of alpha...
