摘　　要：彩色图像色彩丰富,可以很真实地反映景象,而黑白图像能使图像具有历史的沧桑感,在审美上富有更多的内涵和深度,具有自己独特的韵味。提出了基于颜色模型的图像着色算法并在VC++中实现,可将彩色图像转换为黑白图像。将RGB颜色模型、HSI颜色模型和YUV颜色模型的各个分量进行转化、搭配,提出4种转换算法:二值化法、平均值法、最大值法、亮度值法。实验结果表明,所提算法可以快速地将彩色图像转为黑白图像,能使人们在获得彩色图像的同时也获得其对应的黑白图像。Colored images are rich in color and can be a true reflection of the scene. Black and white images have the history vicissitudes and more content and depth in aesthetics with unique charm. Several image coloring algorithms based on color model are proposed and implemented in VC ＋ ＋ to convert colored images into black and white ones. Binarization method,average value method,maximum value method and brightness value method are proposed based on the components＇ conversion and collocation of the RGB color model,HSI color model and YUV color model. The experimental results show that the algorithms can quickly convert the colored images into black and white ones so that people can obtain the corresponding black and white images while obtaining the colored images.
