AN ILLUMINATION INVARIANT TEXTURE BASED FACE RECOGNITION [PDF]

ICTACT Journal on Image and Video Processing, 2013
Automatic face recognition remains an interesting but challenging computer vision open problem. Poor illumination is considered as one of the major issue, since illumination changes cause large variation in the facial features.

Effects of individual and combined doses of added nitrite and nitrate on the quality of dry-fermented sausage [PDF]

Animal Bioscience
Objective We aimed to investigate the impacts of nitrate and nitrite on the salami fermentation process. Methods Experimental groups of dry-fermented sausage were prepared with 100 ppm nitrite (T1), 150 ppm nitrite (T2), and 100 ppm nitrite+50 ppm ...

Rate-Distortion Analysis of Multiview Coding in a DIBR Framework [PDF]

, 2012
Depth image based rendering techniques for multiview applications have been recently introduced for efficient view generation at arbitrary camera positions. Encoding rate control has thus to consider both texture and depth data.

Optimizing feature extraction in image analysis using experimented designs, a case study evaluating texture algorithms for describing appearance retention in carpets [PDF]

, 2011
When performing image analysis, one of the most critical steps is the selection of appropriate techniques. A huge amount of features can be extracted from several techniques and the selection is commonly performed based on expert knowledge. In this paper

Texture-adaptive mother wavelet selection for texture analysis [PDF]

IEEE International Conference on Image Processing 2005, 2005
We discuss the use of texture-adaptive mother wavelets in an adaptive probabilistic wavelet packet approach to texture analysis. First, we present the use of adaptive biorthogonal wavelet packet bases in such ananalysis, thus combining the advantages of biorthogonal wavelets (FIR,linearphase) with those of a coherent texture model.

Effect of alloying (V, Fe, Ge) additions on microstructural evolution in Ti-6Al-4V-based alloys after hot rolling and annealing

Journal of Alloys and Metallurgical Systems
Ti-6Al-4V is the most widely used titanium alloy due to its ability to achieve balanced mechanical properties through microstructural modification via thermomechanical processing.

Quasi-in-situ observation: study on the evolution of the brass-texture in oriented silicon steel during the process of normalizing annealing

Journal of Materials Research and Technology
The presence of the brass texture ({110}) impairs the magnetic properties of oriented silicon steel. However, the mechanism governing the evolution of this texture during normalizing annealing remains unresolved.
