Each directional filter uses a different direction for filtering lines of pixels. For example, for each pixel value of the video block along a line of pixels having a direction corresponding to a directional filter, a difference can be determined between the pixel value and a corresponding pixel value along the line of pixels and outside of the video block. A value for line of pixels is determined as the sum of the absolute values of each of the differences, and a filtered noise value is determined as the sum of the values for the lines of pixels. The directional filter used to determine a lowest one of the filtered noise values for the video block is then selected. The video block is filtered using the selected directional filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Directional deblocking filter","description":"Multiple directional filters are applied against lines of pixels associated with a video block to determine filtered noise values.
