Abstract :
The Landsat TM sensor for thermal infrared measurements, Band 6, has lower resolution than those of other six bands. The authors propose a statistical approach to enhance the resolution of low resolution thermal infrared image by using other band images. They employ a multivariate normal distribution for the joint distribution of 7 band values. The values of Band 6 are predicted by the conditional expectations
