Title

Signal and Information Processing in Hyperspectral Imaging Remote Sensing

Abstract

Hyperspectral imaging (HSI), also known as imaging spectroscopy, is concerned with the measurement, processing, analysis, and interpretation of spectra acquired from a given scene (or specific objects) at spectral resolution of about 1 to10 nm in the visible to near-inferred wavelength range mainly by an air-borne or satellite-borne HSI sensor (hyperspectral scanner), that contains the objects and their background’s spectral data. In recent years, as evolutional development of remote sensing, HSI remote sensing (HSIRS, or HRS: hyperspectral remote sensing) has become a core area within the remote sensing community and has attracted great increasing attention and contributions from wide communities[1-6], such as signal and information processing[6,7], electronic and optical imaging, sensors and automation[1], automatical target recognition (ATR), computer vision and pattern recognition, machine learning, communication, and computer application etc. With HSI data, we can detect and recognize difficult targets appearing at pixel or subpixel level, classify targets with greatly improved accuracy, analyze and identify combined or mixed objects in a pixel. There are great advances in HRS in recent years[1-7], which has resulted in an enormous number of applications, such as airborne and satellite-borne observation of earth (including surveillance, reconnaissance, environment monitoring, land-cover mapping or land-change detection, mineral identification, and camouflage detection, etc.). HSI is also a key technique for planetary exploration, astrophysics, precision remote sensing, medical detection, food inspection and forensics.

 

The signal and information processing for HSIRS contains, Preprocessing (including data calibration, correction, enhancement, fusion, compression, etc.), Signal representation, Feature mining, Classification/Recognition, Unmixing analysis, Fast computation, etc. and the features and classifiers are two main issues for hyperspectral imaging remote sensing applications. In this talk, the signal and information processing for HRS will be briefly addressed with emphasis on feature mining techniques[6-14]. Hyperspectral data is typically composed of hundred spectral measurements for each spatial element of an imaged scene. They form the original set of features. From these features, many new features, such as transformed features, weighted features, derivative features, and spatial texture features, can be formed. The feature mining of HSI remote sensing images for target detection, recognition and classification are divided into multi-pixels, single pixel and sub-pixel levels, which are more natural for target size scale and sensor’s spatial resolution and easier for analysis of feature acquisition techniques. Differing from the traditional frame of only feature selection and feature extraction, a unified frame for the feature mining of HSI remote sensing is summed up as (1) Feature selection which maintains the sensor’s physical meaning; (2) Feature extraction which comprehensively utilizes all the sensed data; and (3) Feature mixing which takes into account of all mixing information over a pixel covering multi small size (sub-pixel) targets. Demonstrated results with several methods for feature mining of real HSIRS data are shown to compare the performances. Moreover, the hot topics in signal and information processing for HSIRS is also outlined. Especially, a framework to integrate spectral, spatial and temporal information by using hyperspectral imaging sensors, video cameras, multiview cameras[15] for more complicated target detection problems will be suggested, which is expected to insight into more valuable research and potential new applications in the area.
