Multicomponent / Multispectral Imagery
Formal JPEG-2000 requirement for a general multiple-component capability (up to 16,384 components) in Part 2 (Extensions).
- The multiple component capability in JPEG 2000 will allow all of the other features of the standard to be applied to multicomponent data; e.g. ROI encoding/decoding, progressive transmission, reversible coding, manipulation of coded image representations, error resilience features.
Supports remote sensing, scientific and medical applications.
- “Multiple components” also includes slices of 3-D volumetric imagery, such as computed (tomographic) images, or other 3-D data sets.
Component decorrelators (KLT, wavelet transform, etc.) will be included as part of the standard to decorrelate across multiple components.
- The standard will support components of different spatial resolutions and optimal allocation of different bit rates to each component.
