Subsampling Based Neighborhood Preserving Embedding for Image Classification

摘要

Abstract-In this paper, a novel image feature extractionalgorithm, called Subsampling based neighborhood preservingembedding (SNPE), is proposed. SNPE aims to preserve theneighborhood of the subsampling image samples. The proposedalgorithm is applied to image classification on Finger-Knuckle-Print database. The experimental results confirm the effectivenessof the proposed algorithm.
