Low-Complexity Lossless Compression of Hyperspectral Imagery via Adaptive Filtering
Onboard compression of hyperspectral imagery is important for reducing the burden on downlink resources. Here we describe a novel adaptive predictive technique for lossless compression of hyperspectral data. This technique uses an adaptive filtering method and achieves a combination of low complexity and compression effectiveness that is competitive with the best results from the literature. Al...
متن کامل3d Wavelet-based Compression of Hyperspectral Imagery
Since hyperspectral imagery is generated by collecting hundreds of contiguous bands, uncompressed hyperspectral imagery can be very large, with a single image potentially occupying hundreds of megabytes. For instance, the Airborne Visible InfraRed Imaging Spectrometer (AVIRIS) sensor is capable of collecting several gigabytes of data per day. Compression is thus necessary to facilitate both the...
متن کاملEfficient Lossless Compression of 4D Hyperspectral Image Data
Time-lapse hyperspectral imaging technology has been used for various remote sensing applications due to its excellent capability of monitoring regions of interest over a period of time. However, large data volume of fourdimensional hyperspectral imagery demands for massive data compression techniques. While conventional 3D hyperspectral data compression methods exploit only spatial and spectra...
متن کاملHyperspectral Image Compression
“Compression of hyperspectral images holds importance because of bad transmission capability of satellites. The project is the implementation of the paper-“Satellite Hyperspectral Imagery Compression Algorithm Based on Adaptive Band Regrouping”. But during the course of the implementation many modifications have been made and some new concepts have been introduced. We have made the given regrou...
متن کاملOverlap-based feature weighting: The feature extraction of Hyperspectral remote sensing imagery
Hyperspectral sensors provide a large number of spectral bands. This massive and complex data structure of hyperspectral images presents a challenge to traditional data processing techniques. Therefore, reducing the dimensionality of hyperspectral images without losing important information is a very important issue for the remote sensing community. We propose to use overlap-based feature weigh...
