基于虚拟仪器的彩色图像单色背景透明化处理

The transparent treatment research of color image with monochrome background which is based on the virtual instrument

在图片的合成应用中需要对图片进行局部的透明化处理。提出了通过虚拟仪器技术,对具有单色背景的彩色人物图像进行处理的一种算法研究。通过将彩色图像的每个像素点分解成RGB三基色后与提取的特征点比对,对每个像素点灰度值运算构建新的图像掩码集,来重构原图像,完成对原彩色图像背景的透明化处理过程。该方法可以应用与背景颜色较为单一并且与人物图像颜色差异性大的图片处理,效果显著。

In the application of synthetic images, it is necessary to achieve local transparent image processing. This thesis describes a method of image processing with the background color of monochromatic characters which is based on the vir-tual instrument technology. Decomposing every pixel of the color image into the red, green,blue three colors and then compare that with the extraction of characteristic points. And structuring new image mask by a new processing method of each pixel to achieve the purpose of the reconstruction of the original image, consequently finishing the background trans-parent process of the original color images. This method can be used to the image processing with relatively single back- ground color and the characters of the big color difference . It works good.
