Contourlet, one of multiscale analysis tool with great property of multi-directionality, locality and sparse approximation, is an excellent 2-dimentional image description approach. Contourlet can be employed as a remote sensing image fusion approach to improve spatial resolution and application through precise capture of edge information from panchromatic image and injection of that into multispectral...
Many image fusion techniques have been proposed so as to achieve optimal resolution in the spatial and spectral domains. The Beijing-1 Micro-Satellite images have their own unique characteristics. The resolution ratio of its multi-spectral image to panchromatic image exceeds 4:1. It is often a challenge to pan-sharpen images with such a large spatial resolution ratio. In this paper, we develop an...

Discriminative common vectors is one of the most successful methods which overcome the small sample size case in Fisher??s linear discriminant analysis. But when we directly use DCV to reduce the dimensions of the ear images, the computational expense of training is still relatively large. A new method is proposed in this paper that the low frequency sub-images are obtained by utilizing two-dimensional...
Video texture can be seen as a new type of media between an image and a normal video. It can provide a continuous, infinitely varying stream of video images. This paper presents a wavelet-based synthesis algorithm that can synthesize new video textures. New frames are constructed based on wavelet coefficients derived from the decomposition of a set of pixel values of neighboring frames. Accordingly,...
