摘要
在对原始图像用小面模型分割的基础上，通过分析图像信噪比与区域噪声各参数之间的约束关系，研究了景像区域误差的模拟生成技术．采用小面模型将图像划分为许多平稳均匀的子区域，并根据给定的信噪比，按照不同的实际需要，在某些子区域内分别叠加区域噪声．
After segmentation of original images by facet model, the simulating generation technique of regional noise of images is presented through analyzing the constraint relationship between signal to noise ratio and the parameters of regional errors. Facet model is adopted to divide an image into many homogeneous subregions. According to given signal to noise ratio and actual need, regional noise is added to some subregions. Results of the research provide a method to evaluate the performance of matching algorithms.
