摘要：
First, the reflection properties of the same object in different bands are obtained by using classification. Then the inter-band predictors are designed to reduce the inter-band correlation. The S + P transform is applied to the difference image to realize spatial decorrelation. Finally, the improved SPIHT is used to realize high-performance lossless encoding. Experimental results show obvious effects and its potential in remote sensing image compression.
