Abstract :
The interferential spectrometer is considered as the next generation of imaging spectrometers in aerial remote sensing. The customary multispectral images compression methods only consider the quality of reconstructed images in spatial domain without concerning the effect in Fourier domain where the application of spectrum is often used, such as substance classification and recognition. Our method WRDO-SPIHT (weighted rate-distortion optimization for SPIHT) is proposed based on the relationship between the distortion in Fourier domain and compression in spatial domain.
