MATLAB Program for Reading ENVI Remote Sensing Images

This program is developed in MATLAB for reading remote sensing images, particularly supporting the ENVI file format. It utilizes MATLAB's file I/O functions and image processing toolbox to efficiently handle hyperspectral and multispectral data. The implementation includes specialized functions for parsing ENVI header files (.hdr) and reading associated binary data files, ensuring proper band interleave format recognition (BIL, BIP, BSQ). Beyond basic file reading, the program incorporates advanced image processing algorithms including smoothing filters (Gaussian, median), frequency-domain filtering techniques, and contrast enhancement methods (histogram equalization, adaptive contrast stretching). The architecture supports multiple image format import/export capabilities through MATLAB's imread/imwrite functions with format converters, enabling flexible processing of remote sensing data. The object-oriented design allows for easy extension of functionality through additional method implementations. Overall, this program serves as a practical toolkit that significantly assists in remote sensing image processing workflows, providing both core reading functionality and essential preprocessing operations.
