- W2134455835 abstract "In this paper, a fast infrared face recognition method using blood perfusion conversion and curvelet transformation is proposed. Firstly, to get the good performance of infrared face recognition from the biological feature, thermal images are converted into blood perfusion domain by blood perfusion model. Secondly, curvelet transform has better directional and edge representation abilities than widely used wavelet transformation and other classic transformations. Inspired by these attractive attributes of curvelets in sparse representation of the images, we introduce the idea of decomposing images into their curvelet subbands to extract the principal representative feature, which saves the computational complexity and storage units. Finally, the nearest neighbor classifier is chosen to get the method recognition result. The experiments illustrate that compared with those traditional methods based on PCA, the proposed method has better performance and requires fewer computations and memory units." @default.
