Thermal infrared measurements of Band 6 acquired by Landsat TM sensor have lower spatial resolution than those of the other six bands. In this paper, we propose a statistical approach to enhance the resolution of low spatial resolution image by using remaining bands. We employ a mnltivariate normal distribution for the seven band values. The values of Band 6 are predicted by the conditional expectations. Validity of our procedure is examined by mean squared errors based on actual images.
