Paper Abstract

Fusion of panchromatic image with multispectral image provides high-resolution data for geographical information system (GIS). This paper presents a method to fuse panchromatic image with multispectral image using B-spline tight frame. The fused image is obtained by processing the B-spline discrete tight frame transform subimages. Fusion of QuickBird remote sensing images is carried out. The spectral resolution of the fused image is high, and the spatial resolution is superior to the one corresponding to discrete wavelet transform (DWT) method as well as a recently reported discrete tight frame transform (DTFT) method. Moreover, this method almost removes the ring artifacts existing in DWT method and DTFT method, thus remarkably improving the visual effects of the fused images.
