CODING AND DECODING UTILIZING CONTEXT MODEL SELECTION WITH ADAPTIVE SCAN PATTERN

摘要

There is a coding. The coding may include preparing video compression data based on source pictures. The preparing may include partitioning the source pictures into coding units and/or generating a transform unit having a transform array. The preparing may also include processing the generated transform unit. The processing may include generating a significance map, having a significance map array with y-x locations corresponding to the y-x locations of the transform array. The processing may also include determining, utilizing a scanning pattern, a context model for coding a significance map element of the plurality of significance map elements based on a value associated with at least one coded neighbor significance map element of the plurality of significance map elements in the significance map array. There is also a decoding including processing video compression data which is generated in the coding.
