When the moon has gone down and the suncomes up,the whole world fills with color.Somethings are yellow like egg yolks and cheese,lemons and bananas,and dandelions too. Lots of things are red.Stop lights,someflowers,fire engines,and red foxes.Green is thecolor of many frogs and fish,spring leaves andgrass.What’s blue?The color of water on the earth-blue eyes and blue skies,blue birds,blueberr-ies.and of course.blue ieans! 相似文献

INTRODUCTION Digital matting and compositing is a popular technique in the film industry, with which we can separate a foreground object, including both its color and opacity, from a background image. The descrip- tion of the separated foreground object is named digital matte. Smith and Blinn (1996) proposed the blue screen matting technique. They formally de- scribed the mathematical solution to the digital mat- ting problem, when either some constraints on the foreground color or a pair… 相似文献

In the novel The Color Purple,purple is a color that Alice Walker uses to symbolize the main character:Celie.In color psychology,purple is a complex color.At first,it has two contradictory symbolic meanings just as Celie’s personality.Secondly,purple is a color which blends blue and red.In western countries,red symbolized man and blue symbolized woman.However,Celie is a person who has both man’s and woman’s characteristics.At last,purple is a changeable color.Celie’s early misery life is like dark purple which has more of a passive meaning.And her later life turns out to be light purple which symbolizes more of the beautiful things.And the turning of her life may be viewed as awakening of womanism. 相似文献

A novel color compensation method for multi-view video coding （MVC） is proposed, which efficiently exploits the inter-view dependencies between views with the existence of color mismatch caused by the diversity of cameras. A color compensation model is developed in RGB channels and then extended to YCbCr channels for practical use. A modified inter-view reference picture is constructed based on the color compensation model, which is more similar to the coding picture than the original inter-view reference picture. Moreover, the color compensation factors can be derived in both encoder and decoder, therefore no additional data need to be transmitted to the decoder. The experimental results show that the proposed method improves the coding efficiency of M VC and maintains good subjective quality. 相似文献

能抵抗RQP分析的密写技术 总被引：6，自引：0，他引：6
A new steganographic approach for 24-bit color images that can resist the RQP(raw-quick-pairs)steganalysis is described.The technique is based on modification of color triplets such that the existing color palette is not excessively expanded or even reduced.In this way,numbers of unique colors and pairs of close-colors in the image do not rise significantly.This invalidates the RQP analysis.Experimental results are presented to support the argument. 相似文献

A neural-statistical approach to the reconstruction of novel viewpoint image general regression neural networks(GRNN) is presented.Different color value will be obtained by watching the same surface point of an abject from different viewpoints due to specular reflection,and the difference is related to the position of viewpoint.The relationship between the position of vewpoint and the color of image is non-linear,neural network is introduced to make curve fitting,where the inputs of neural network are only a few calibrated images with obvious specular reflection.By training the neural network,network model is obtained.By inputing an arbitrary virtual viewpoint to the model,the image of the virtual viewpoint can be computed.By using the method presented here,novel viewpoint image with photo-realistic property can be obtained,especially images with obvious specular reflection can accurately be generated.The method is an image-based rendering method,geometric model of the scene and position of lighting are not needed. 相似文献

In Chinese and western culture,color words are both as many as the sands in the Ganges river and stars in the blue sky.And its meanings have something in common and also something that is different.To find out the same points and differentias and to avoid mistakes in intercommunication,the writer will analysis the meanings of some main color words and makes an explain for the differences from the aspect of culture between Chinese and western countries by the means of comparison and analysis.After the analysis,the writer discovers that the meanings of the colors are basically different except the purple,and which are deeply affected by their each culture.And the meanings of them would change in the situation of intercommunication.Therefore,we should use these words properly. 相似文献

For the typical color detects of polysilicon wafers, i.e., edge discoloration, color inaccuracy and color non-uniformity, a new integrated machine vision detection method is proposed based on an HSV color model. By transforming RGB image into three-channel HSV images, the HSV model can efficiently reduce the disturbances of complex wafer textures. A fuzzy color clustering method is used to detect edge discoloration by defining membership function for each channel image. The mean-value classi- fying method and region growing method are used to identify the other two defects, respectively. A vision detection system is developed and applied in the produc- tion of polysilicon wafers. 相似文献

Color can make our life colorful not only by its physical attributions, but also by its extended meanings derived from cultural differences. There is striking richness in the cultural connotations of color terms, which can vivify our language. Since language is a reflection of culture, in order to have a good master of the English culture and overcome misunderstandings in communication, a better understanding of indications and cultural connotations of some typical color terms is a prerequisite for English learners.However, because English-speaking countries have certain geographic environments, customs, ways of thinking, religious beliefs, regimes, literature and arts and ways of living, there is no surprise that colors are described in some specific ways and have some particular meanings in that countries.The thesis will mainly deal with cultural connotations of some typical color terms and their usage in language. 相似文献

A new blue electroluminescent material,distyrylarylene(DSA)derivative,4,4‘-bis[2,2-(1-naphthyl,phenyl)vinyl]-1,1-biphenyl(NPVBi)is designed and synthesized.The DSA derivative shows better thermal stability because of its high glass transition temperature.A blue organic light emitting diode(OLED0with the structure ITO/TPD/NPVBi/Alq/LiF/Al is studied.The electroluminescent(EL0spectrum of the OLED exhibits that light emission originates from NPVBi with a peak at 460nm,its Commission Internationale de l‘Eclairage(CIE)color coordinates are x=0.16,y=0.15,and showing independence of CIE color coordinates on current density.The new DSA derivative is expectable as a new candidate for blue light emitter in OLEDs. 相似文献

Diabetic retinopathy (DR) is one of the most important causes of visual impairment. Automatic recognition of DR lesions, like hard exudates (EXs), in retinal images can contribute to the diagnosis and screening of the disease. To achieve this goal, an automatically detecting approach based on improved FCM (IFCM) as well as support vector machines (SVM) was established and studied. Firstly, color fundus images were segmented by IFCM, and candidate regions of EXs were obtained. Then, the SVM classifier is confirmed with the optimal subset of features and judgments of these candidate regions, as a result hard exudates are detected from fundus images. Our database was composed of 126 images with variable color, brightness, and quality. 70 of them were used to train the SVM and the remaining 56 to assess the performance of the method. Using a lesion based criterion, we achieved a mean sensitivity of 94.65 and a mean positive predictive value of 97.25 . With an image-based criterion, our approach reached a 100 mean sensitivity, 96.43 mean specificity and 98.21 mean accuracy. Furthermore, the average time cost in processing an image is 4.56 s. The results suggest that the proposed method can efficiently detect EXs from color fundus images and it could be a diagnostic aid for ophthalmologists in the screening for DR. 相似文献
