Convert FIT to J2K

The Flexible Image Transport System (FIT) file format, widely used in the field of astronomy and imaging, is designed for the storage, transmission, and processing of digital images and data. Developed in the late 1970s by the International Astronomical Union (IAU), the FIT format has become the standard for storing complex data arrays, including metadata. FIT files are particularly valued for their ability to preserve high-precision scientific data and extensive headers, making them indispensable in both professional and amateur astronomical research.

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
