Abstract


With the increase in incidence at night , the increasingly high demand for night vision surveillance system to capture the image effect to improve the effect of night vision surveillance is needed to solve the problem of color transfer technique is proposed in this context . In this paper, the color transfer algorithms color feature extraction based on block thinking , based on GLCM texture feature extracted color transfer algorithms and algorithm based on color image fusion and image retrieval technology transfer color grayscale images . Grayscale image of the color of the color characteristics of a color image is passed to the other in a grayscale image, the gray target image having a similar color to the source color image . This algorithm shortcomings of poor adaptability based on traditional color transfer algorithm proposed in this paper, color transfer algorithm calculated by the color and texture features of the image in the image library , find the target image to match the image as color source image transfer , to achieve the automatic matching of the source and destination images , and improve the algorithm 's ability to adapt , but also reduce human involvement in the color transfer process , improve the color transfer efficiency , but also improve the color transfer effects , and color transfer algorithm and block - based thinking to extract color features extracted texture features based on GLCM color transfer algorithm . According to the characteristics of night vision image directly night vision image colorization of grayscale images , color transfer effects is less than ideal . In this case , we use the first collected to shimmer and infrared image fusion, to improve the definition of the target image . Image after image fusion technology as a target image , the fusion image color processing , and then by calculating to find matches of the source image with the target image , and finally completed the color delivery . In this paper, the VS2008 software development platform to design a color transfer software to verify the feasibility of the proposed color transfer algorithm through the simulation of multiple images .
