==REDUCING BLOCKINESS FOR CODECS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17956444 titled 'REDUCING BLOCKINESS FOR CODECS

==Simplified Explanation==

The patent application describes a method for processing image frames by applying a filter to motion compensation units within a prediction unit. It also describes a method for deblocking a current block by applying a deblocking filter to a reference block, a predicted block, or a reconstructed prediction unit.

* The method involves receiving an image frame with coded blocks and determining a prediction unit (PU) from these blocks.
* Within the PU, one or more motion compensation units are arranged in an array.
* A filter is applied to the boundaries of the motion compensation units.
* Additionally, the method involves receiving a reference frame with a reference block and determining the timing for deblocking a current block.
* Motion compensation is performed on the reference frame to obtain a predicted frame with a predicted block.
* Reconstruction is performed on the predicted frame to obtain a reconstructed frame with a reconstructed PU.
* At the timing for deblocking the current block, a deblocking filter is applied to the reference block, predicted block, or reconstructed PU based on one or more parameters.

Potential applications of this technology:

* Video compression and encoding: The method can be used in video compression algorithms to improve the quality of compressed video by applying filters to motion compensation units and deblocking blocks.
* Video streaming: By enhancing the quality of video frames, this technology can improve the viewing experience in video streaming services.
* Video editing and post-production: The method can be utilized in video editing software to enhance the quality of frames during editing and post-production processes.

Problems solved by this technology:

* Image artifacts: By applying filters to motion compensation units and deblocking blocks, this technology helps reduce image artifacts such as blockiness and blurring in compressed video frames.
* Motion compensation accuracy: The method improves the accuracy of motion compensation by applying filters to the boundaries of motion compensation units, resulting in better prediction and reconstruction of frames.

Benefits of this technology:

* Enhanced video quality: By applying filters to motion compensation units and deblocking blocks, the method improves the overall quality of video frames, resulting in a better viewing experience for users.
* Efficient video compression: The use of filters in motion compensation and deblocking helps optimize video compression algorithms, leading to more efficient encoding and reduced file sizes without significant loss in quality.
* Improved motion estimation: By applying filters to motion compensation units, the method improves the accuracy of motion estimation, resulting in better prediction and reconstruction of frames.
