This paper presents a new approach for off-line signature verification. The proposed system is based on global, grid, ink distribution and texture features. The Boosting algorithm is applied to train and integrate multiple classifiers, and the distance-based classifier used as the base classifier corresponding to each feature set. Adaptive threshold is associated with individuality. Experimenta...

While many computer vision algorithms can be used to determine surface orientation information, most require extensive processing (e.g. texture based method). In this paper we demonstrate that under xation, the ratio of angular disparity measures and knowledge of eye position can be used to obtain an estimate of surface orientation. A sensitivity analysis based on accuracy of eye position contr...

The authors study the effect of the spontaneous polarization PS of a ferroelectric liquid crystal mixture with compensated helix and of the thickness of the alignment layer da on the analog switching in a cell. The quality of analog switching is established in terms of its contrast ratio, texture in the dark state, and the electrostatic energy. The latter approximates to PS da for da d thicknes...

This paper presents an effective approach to generate a set of small textures from an input texture that can be tiled together to synthesize large textures. Such a small set can be useful in texturing any large area realistically and efficiently while consuming only a small amount of texture memory. Our approach is advantageous in its ability to generate a smaller number of tiles that can embed...

the evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (abe). the microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°c were characterized. the results showed that after single abe pass at 100°c an ultrafine/nano grained microstr...

The authors proposed the texture unit-based texture spectrum approach in 1990, which has been used for texture analysis, including texture characterization, texture classification, texture edge detection, and textural filtering. One of the most important disadvantages related to this method is the large number of texture units (6,561) and its redundancy. This paper aims at simplifying the origi...

Abstract The objective of this study was to research the adaptability insects in food products. created hamburger patties were made with pork meat and insect batter ( Zophobas morio ) a 50:50 ratio color, pH value, water-holding capacity, roasting loss, texture, microbiological traits studied during ten days refrigerated storage (5 °C, vaccum packaging, air cooling). Similar products have alrea...
