The Fresnel lens arrays, which can be used as the alternative of microlens arrays for integral imaging, were designed and fabricated. Their imaging properties for different colors were investigated, and a design based on the Fresnel lens arrays with chromatic dispersion is proposed.
During the manufacturing processes of the thin-film transistor liquid-crystal display (TFT-LCD) panel, red, green, and blue (RGB) color filter coatings undergo the layer-adding process which causes the rough surfaces between the layers. The rough surfaces make acquiring an accurate measurement of the optical properties and thickness much more difficult because the scattering effects occur...
Machine vision system, which is an important part in robotic soccer. During the period of the competition, for real color, it is easily to cause the robot vision unable, for example, misrecognizing or error recognition under the different brightness. For solving this problem, we propose a fuzzy color detection to improve this problem in this paper. For examining the camera's erection, the camera might...
The vehicle shadow's detection and elimination work basically for extracting and tracking the vehicle characteristics, and it also plays a very important role in highway video surveillance and incident detection, affecting the post-processing of video image directly, such as vehicle tracking and speed measurement. On study of Kimmel variational and multi-scale Retinex algorithm to eliminate the vehicle...
Teaching resources are usually massive, complex, hybrid and distributed. In order to search and utilize images from teaching resources with high efficiency, this paper introduced how to use CBIR (Content-based Image Retrieval) to search images from teaching resources, and design a image retrieval system for Teaching resources, it emphasizes on the analysis of relevance feedback algorithm based on...
Real color images are images with noise. The application of gray-scale image enhancement methods in the three-channel of images (R, G, B), on the one hand, increased noise, on the other hand, tended to have a color deviation, which impacted the effect of enhancement. Therefore in view of the difference of human visual system sensitivity of the hue, saturation, luminance and image noise affecting differently...
Real color images are images with noise. The application of gray-scale image enhancement methods in the three-channel of images (R,G,B), on the one hand, increased noise, on the other hand, tended to have a color deviation, which impacted the effect of enhancement. In view of human visual system is more sensitive to lightness than hue, saturation and noise affects lightness more than a,b color channel...
Because the most algorithms of real color image enhancement did not relate to the spectral sensitivity of most people vision, the color restoration functions of some real color image enhancement algorithms are greatly at random and not proved, and the enhanced real color images which are based on illumination-reflectance model have the loss of details and the dasiahalospsila, we proposed a new algorithm...

Because the color restoration functions of real color image enhancement are greatly at random and not proved, and the enhanced real color images which are based on illumination-reflectance model have the loss of details and the 'halos', we proposed a new algorithm to overcome these disadvantages. Firstly, we transform the real color image from RGB space to HSV space which is approximately orthonormal...
