This paper presents a real-time global illumination method for static scenes illuminated by arbitrary, dynamic light sources. The algorithm obtains the indirect illumination caused by the multiple scattering of the light from precomputed light paths. The indirect illumination due to the precomputed light paths is stored in texture maps. Texture based representations allow the GPU to render the ...

We introduce halftoning as a general primitive for real-time non-photorealistic shading. It is capable of producing a variety of rendering styles, ranging from engraving with lighting-dependent line width to pen-and-ink style drawings using prioritized stroke textures. Since monitor resolution is limited we employ a smooth threshold function that provides stroke antialiasing. By applying the ha...

Current 3D imaging solutions are often based on rather specialized and complex sensors, such as structured light camera/projector systems, and require explicit user cooperation for 3D face scanning under more or less controlled lighting conditions. In this paper, we propose a cost effective 3D acquisition solution with a 3D space-time superresolution scheme, using a calibrated stereo rig couple...

We present a deep neural network for removing undesirable shading features from an unconstrained portrait image, recovering the underlying texture. Our training scheme incorporates three regularization strategies: masked loss, to emphasize high-frequency features; soft-shadow which improves sensitivity subtle changes in lighting; and shading-offset estimation, supervise separation of method dem...

Human skin is made up of multiple translucent layers and rendering of skin appearance usually acquire complex modeling and massive calculation. In some practical applications such as 3D game development, we not only approximate the realistic looking skin but also develop efficient method to implement easily for meeting needs of real-time rendering. In this study, we solve the problem of wrap li...

This paper presents an overview of techniques for generating photoreal computer graphics models of real-world places and objects. Our group’s early efforts in modeling scenes involved the development of Façade, an interactive photogrammetric modeling system that uses geometric primitives to model the scene, and projective texture mapping to produce the scene appearance properties. Subsequent wo...

The field of automatic image recognition presents a variety of difficult classification problems involving the identification of important scene components in the presence of noise, changing lighting conditions, and shifting view points. This chapter describes part of a larger effort to apply machine learning techniques to such problems in an attempt to automatically generate and improve the cl...

this study was conducted to determine the effects of increasing lighting after peak production on eggs production and hatchable eggs in broiler breeder hubbard f15. in this research we used from 4 growing saloons, that in per saloons were 5250 hubbards broiler breeder hens. in this experiment we used by line design way of glm for analysed data, that we considered the effects of two parameters, ...

Hatching is a shading technique in which tone is represented by a series of strokes or lines. Drawing using this technique should follow three criteria: the lighting, the object geometry and its material. These criteria respectively provide tone, geometric motif orientation and geometric motif style. We present a GPU real time approach of hatching strokes over arbitrary surfaces. Our method is ...
