Image coding method and apparatus, and image decoding method and apparatus
摘要:
In an image coding apparatus, a ROI setting unit sets a ROI region in an image. An entropy coding unit entropy-codes the image. A ROI information coding unit encodes information for specifying the ROI region. A codestream generator generates a codestream in a manner that the coded image and the coded information are explicitly included in the codestream. When a plurality of ROI regions are set in the image, the information may include a degree of priority.
