DEBLOCKING FILTERING CONTROL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18150393 titled 'DEBLOCKING FILTERING CONTROL

Simplified Explanation

The patent application describes a method for filtering pixels in a video frame based on their values and their position relative to neighboring blocks. Here are the key points:

  • The method calculates a first filter decision value for a block of pixels in a video frame by analyzing the pixel values in the first line of pixels within the block.
  • It also calculates a second filter decision value for the block by analyzing the pixel values in the corresponding first line of pixels in a neighboring block.
  • The first filter decision value determines how many pixels in a line of pixels within the block should be filtered, considering the block boundary.
  • Similarly, the second filter decision value determines how many pixels in the corresponding line of pixels in the neighboring block should be filtered, relative to the block boundary.

Potential applications of this technology:

  • Video compression: The method can be used to improve video compression algorithms by selectively filtering pixels based on their values and their relationship with neighboring blocks.
  • Image enhancement: The technique can be applied to enhance the quality of images by selectively filtering pixels in a way that preserves important details while reducing noise or artifacts.

Problems solved by this technology:

  • Efficient filtering: The method allows for a more efficient filtering process by dynamically determining the number of pixels to be filtered based on their values and their position relative to neighboring blocks.
  • Preservation of important details: By selectively filtering pixels, the technique helps preserve important details in the video frame or image while reducing unwanted noise or artifacts.

Benefits of this technology:

  • Improved video quality: The method can lead to improved video quality by selectively filtering pixels, resulting in reduced noise and improved clarity.
  • Enhanced compression efficiency: By filtering pixels based on their values and their relationship with neighboring blocks, the technique can improve the efficiency of video compression algorithms, leading to smaller file sizes without significant loss of quality.


Original Abstract Submitted

A first filter decision value is calculated for a block of pixels in a video frame based on pixel values of pixels in a first line of pixels in the block. A second filter decision value is also calculated for the block based on pixel values of pixels in a corresponding first line of pixels in a neighboring block in the video frame. The first filter decision value is used to determine how many pixels in a line of pixels in the block to filter relative to a block boundary between the block and the neighboring block. The second filter decision value is used to determine how many pixels in a corresponding line of pixels in the neighboring block to filter relative to the block boundary.
