JPEG2000 Compression Package for MATLAB

The JPEG2000 compression package commonly used in MATLAB provides an efficient image compression algorithm implementation. This package enables storage of image files with significantly reduced file sizes while maintaining high visual quality. Users can control compression ratios and image fidelity by adjusting compression parameters through MATLAB functions like imwrite with quality settings or wavelet transformation parameters. The algorithm employs discrete wavelet transform (DWT) for multi-resolution analysis and embedded block coding with optimized truncation (EBCOT). JPEG2000 supports both lossy and lossless compression modes, with key functions including imread for decompression and format-specific options for progressive decoding. Its multi-resolution encoding capabilities and region-of-interest support make it widely applicable in image processing and transmission fields, particularly in medical imaging and streaming applications where bandwidth optimization is crucial.
