Abstract:
1. A method of reconstructing a signal at a higher level of quality in a hierarchy, the method comprising: selecting an element from a rendition of the signal at a first level of quality to upsample into multiple elements of a rendition of the signal at a second level of quality, the second level of quality being higher than the first level of quality; producing a metric based on settings of elements in a vicinity of the selected element in the rendition of the signal at the first level of quality, the metric defining a boundary between a first set of elements in a vicinity of the selected element and a second set of elements in a vicinity of the selected element; Dividing the multiple elements of the rendition of the signal at the second level of quality into subdivisions using the metric; and Utilizing areas of the subdivisions of the multiple elements as defined by the metric to calculate settings for the multiple elements in the signal at the second level of quality.
