Abstract: A better rate distortion ratio is achieved by making interrelationships between coding parameters of different planes available for exploitation for the aim of redundancy reduction despite the additional overhead resulting from the need to signal the inter-plane prediction information to the decoder. In particular, the decision to use inter plane prediction or not may be performed for a plurality of planes individually. Additionally or alternatively, the decision may be done on a block basis considering one secondary plane.

Abstract: Methods and apparatus are provided for creating one or more compressed image tiles based on a compressed file that describes a digital image. In particular, the compressed image tiles are created without fully decompressing the compressed file. Each compressed image tile includes data corresponding to a portion of the digital image, and is independent of other compressed image tiles (i.e., may be decompressed without decompressing any other tile). In response to requests to display a desired portion of the digital image at a specific resolution, the compressed image tiles corresponding to the desired portion and the specified resolution are communicated via a band limited communication channel. In this regard, the portions of the digital image may be quickly communicated and displayed, without having to wait for the entire compressed file to be communicated over the band limited channel.

Abstract: Provided a resolution conversion method, which converts the resolution of an image by using orthogonal transform, and in which block noise reduction processing is performed according to the increasing magnification of the image.
