A processing of border pixel from map originate problem while work with outline objects segmentation algorithm on bitmap images, which are based 2D convolution operation. The correspond addition set pixels outside matrix image. This is actual also in other algorithms, have a common feature – level importance defined by multi used nonlinear filters to and then union few images without distortion...

Tunable leaky-mode resonant silicon-nitride pixels providing red/green/blue spectral lines are analyzed. Critical dimensions, rate of tuning, linewidths, and polarization properties are quantified. ©2007 Optical Society of America OCIS codes: (050.1950) Diffraction gratings; (310.2790) guided waves; (120.2440) filters. Microelectromechanical systems (MEMS) methods are useful for tuning the spec...

In this paper we show how to use two-colored pixels as a generic tool for image processing. We apply twocolored pixels as a basic operator as well as a supporting data structure for several image processing applications. Traditionally, images are represented by a regular grid of square pixels with one constant color each. In the twocolored pixel representation, we reduce the image resolution an...

Christophe Schlick Laboratoire Bordelais de Recherche en Informatique Talence, FRANCE We present a picture encoding technique for RGB color images that uses nonlinear quantization of pixel values to achieve a much higher dynamic range than the usual 256 values per primary color. The encoding uses only 24 bits per pixel. } Introduction } Global illumination algorithms (radiosity, Monte Carlo ray...

Dense stereo vision has evolved into a powerful foundation for the next generation of intelligent vehicles. The high spatial and temporal resolution allows for robust obstacle detection in complex inner city scenarios, including pedestrian recognition and detection of partially hidden moving objects. Aiming at a vision architecture for efficiently solving an increasing number of vision tasks, t...

Hemispherical photography is a well-established method to optically assess ecological parameters related to plant canopies; e.g. ground-level light regimes and the distribution of foliage within the crown space. Interpreting hemispherical photographs involves classifying pixels as either sky or vegetation. A wide range of automatic thresholding or binarization algorithms exists to classify the ...

A new algorithm for phase unwrapping of phase maps with noise or logical inconsistencies is proposed. It is based on the use of an adaptive threshold and the second difference of the locally unwrapped phase as a selection criterion for the pixels to be processed.
