Reading IMG Format Remote Sensing Data in MATLAB

In remote sensing image processing, MATLAB serves as a widely utilized tool that can conveniently read and process various remote sensing data formats. Among these, the IMG format stands out as a commonly used remote sensing data format. To facilitate advanced research in remote sensing algorithms, we need to develop a MATLAB program capable of reading IMG format remote sensing data. This program typically involves using MATLAB's file I/O functions and image processing toolbox. Key implementation steps include: 1. File header parsing to extract metadata information 2. Data dimension recognition and buffer allocation 3. Binary data reading using fread() function with appropriate data type specification 4. Data reshaping and georeferencing information processing 5. Image visualization and quality validation The program helps researchers better understand the principles of remote sensing image processing and conduct in-depth studies of remote sensing algorithms, thereby establishing a foundation for more complex remote sensing data processing tasks. Through proper data reading implementation, users can access pixel values, spatial information, and spectral characteristics essential for algorithm development.
