Description

For the case of horisontal edges the order of 8 and 4 sample boundary checks is wrong (for vertical edges it is corrrect). The order of the checks shall be as follows for horisontal edges and then also change the equation numbers correspondly:

– Otherwise, if one or more of the following conditions are true:
– ( y + 4 ) is larger than or equal to nCbH,
– edgeTbFlags[ x ][ y − 4 ] is equal to 1,
– edgeTbFlags[ x ][ y + 4 ] is equal to 1,
the following applies:
maxFilterLengthPs[ x ][ y ] = 1 (8 1043)
maxFilterLengthQs[ x ][ y ] = 1 (8 1044)

– Otherwise, if one or more of the following conditions are true:
– yEdge is equal to 1,
– yEdge is equal to ( nCbH / 8 ) − 1,
– edgeTbFlags[ x ][ y − sbH ] is equal to 1,
– edgeTbFlags[ x ][ y + sbH ] is equal to 1,
the following applies:
maxFilterLengthPs[ x ][ y ] = 2 (8 1045)
maxFilterLengthQs[ x ][ y ] = 2 (8 1046)
