Efficient encoding/decoding in the decomposition and recomposition of a high resolution image utilizing its low resolution replica

Abstract From the Canadian patent

Abstract, More efficient encoding/decoding in decomposing and recomposing a high resolution image is obtained by employing a unique prediction arrangement. The prediction arrangement determines whether high resolution pixels to be recomposed from low resolution pixels from a low resolution replica of the high resolution are so-called typically predictable or non-typically predictable by using general prediction rules. The general prediction rules are also employed to determine if any of the typically predictable high resolution pixels would be improperly recomposed. Such high resolution pixels which would be improperly recomposed are identified as exceptions. It is noted that so-called …
