摘要:An objective grading method using a Computer Vision System (CVS) for mangoes is proposed. Red peel was selected using two types of color space values at chroma = 22 and hue angle = 52 ° . Eighteen out of 25 fully-ripened fruits were graded as “excellent,” determined by ...

摘要:Color transformation from RGB to CMYK is a significant problem in color reproduction. Since black ink is a redundant component, it is impossible to find a unique set of CMYK ink quantity suitable for an input RGB color. This paper proposes an algorithm for UAR, using the direct c...

摘要:A fiber-optic correlation processing system is constructed to examine the fluctuation characteristics of optical waves guided in an externally perturbed birefringent fiber. Optical heterodyne detection processes by use of a laser beam with orthogonal linearly polarized two-freque...

摘要:We are developing a spectral characteristics database for evaluating color reproduction in image input devices. The database is designed so that spectral characteristics are systematically divided by category, according to the purpose to which they are to be applied, and every ca...

摘要:Abstract This paper proposes a novel foreground detection method which estimates the color changes in shadow regions by using a solar spectral model. In conventional method, since it is assumed that only brightness changes from background in shadow regions, shadow regions are ext...
