局部线性嵌入算法在图像处理中的应用

摘要

In order to avoid light, gesture, appendages and other factors on the same image matrix and identification of differences, using the locally linear embedding (LLE) algorithm, first image library of pre-illumination image, and then into the use of LLE operation with low-dimensional image features, and the simulation results obtained not only the image recognition to prevent light and other factors, but also make image recognition rates increased significantly, resulting in locally linear embedding algorithm using image processing results.%为了避免光照、姿态、附属物等因素对同一个图像矩阵的差异和识别的影响,采用了局部线性嵌入(LLE)算法,首先对图像库里的图像进行光照预处理,再进用LLE运算得到低维图像特征,并通过仿真实验获得了既能使图像识别避免光照等因素的影响,又能使图像识别率有了大幅度的提高,从而得到利用局部线性嵌入算法时图像进行处理的结论.
