Abstract:

Hyperspectral images generally have lowspatial resolution due to limitations of the imaging spectrometer. In this paper, VSC-CNMF is designed to produce a fused image from hyperspectral and multi-spectral images. An end-member smallest volume and abundance sparseness constrained NMF (VSC-CNMF) algorithm is proposed based on the physical characteristics of remote sensing images. We match the end-member and abundance of two types of images by spectral and spatial degradations, and get the fused image with high spatial and spectral resolution according to some un-mixing update rules. Simulation results show that fused images with higher spatial and spectral quality can be obtained with VSC-CNMF.

Key words: non-negative matrix factorization, hyperspectral image, sparseness constraint, spatial resolution, minimum volume constraint, image fusion
