Abstract
Techniques for data processing in an edge offset mode of sample adaptive offset are provided. The techniques include: traversing reconstructed pixels in a coding tree block, and calculating a residual value between each reconstructed pixel and original pixel; traversing all first reconstructed pixels in a non-boundary part of the coding tree block, and calculating a category of each traversed first reconstructed pixel in each direction; traversing all second reconstructed pixels in a boundary part of the coding tree block, and calculating a category of each traversed second reconstructed pixel along a single direction; and calculating an accumulated residual value of reconstructed pixels along the four directions and an accumulated number of reconstructed pixels under the category based on the category of each first reconstructed pixel the edge offset modes along the four directions, the category of each second reconstructed pixel along the single direction, and each residual value.
