Abstract :
We fused RADARSAT images and SPOT panchromatic images by a wavelet transform in order to improve the accuracy of classification of water areas. Fused images not only maintained the characteristic of the SAR image (low pixel value) but also had improved boundary information. This leads to an accurate method to classify water areas.
