JPEG 2000 is an image compression standard designed to supersede the original JPEG standard. It offers superior compression performance, meaning it can achieve higher image quality at the same file size or smaller file sizes at the same image quality. Unlike JPEG, which uses a Discrete Cosine Transform (DCT) based compression, JPEG 2000 employs wavelet transform technology. This allows for features like progressive decoding (images can be viewed at low resolution and gradually improve), region-of-interest coding (specific areas of an image can be encoded with higher quality), and lossless compression (no data is lost during compression). JPEG 2000 is particularly well-suited for applications where image quality and compression efficiency are critical, such as medical imaging, archiving, and high-resolution photography. It supports both lossy and lossless compression, providing flexibility for different use cases. The standard also includes features for error resilience, making it robust in noisy environments. While JPEG 2000 offers significant advantages, its adoption has been slower than expected, partly due to its computational complexity and licensing issues in the past. However, it remains a valuable option for specific applications where its advanced features are beneficial.
