面向缺失像素图像集的修正拉普拉斯特征映射算法
Modified Laplacian Eigenmap Algorithm for Missing Pixels Image Set
摘要
Abstract
In this paper,we propose a modified laplacian eigenmaps algorithm for the missing pixel images.The algorithm takes the missing pixel image set as a vector set,then using the cosine similarity between vectors to measure the distance between missing pixel images.Further,a new weight constructor function is proposed.Experiments on several sets of standard test data sets show that the modified laplacian eigenmaps algorithm can well excavate the intrinsic manifold structure of the missing pixel images and weaken the negative effects of missing pixels.关键词
