Deblocking filtering method and deblocking filter

摘要

Embodiments of the present invention provide deblocking filtering methods and deblocking filters. The deblocking filtering method comprising the steps of: determining a first filtering offset value of the pixel to be filtered in accordance with a current pixel value of a pixel to be filtered in an image block and a pixel value of a pixel in the first neighboring partition of the pixel to be filtered; Performing a prediction on a pixel value of the filtering target pixel according to a pixel value of a pixel in the second neighboring partition of the filtering target pixel to obtain a predicted value of the filtered value of the filtering target pixel; And determining an actual filtered value of the pixel to be filtered according to the current pixel value, the first filtering offset value, and the predicted value of the filtered value. In an embodiment of the present invention, the actual filtered value is combined with the current pixel value and the first filtering offset value to obtain the predicted value of the additional filtered value. In this way, the overall smoothness of the filtered signal waveform can be improved.
