METHODS PROVIDING ENCODING AND/OR DECODING OF VIDEO USING REFERENCE VALUES AND RELATED DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240098256 titled 'METHODS PROVIDING ENCODING AND/OR DECODING OF VIDEO USING REFERENCE VALUES AND RELATED DEVICES

Simplified Explanation

The abstract describes a method for decoding an encoded video sequence by calculating reference values and using interpolation to generate filtered pixel values for adjacent blocks of images.

• First and second adjacent blocks of an image are provided.
• A line of pixels across the boundary between the blocks is defined.
• Reference values are calculated based on pixels from each block.
• Filtered pixel values for each pixel on the line are calculated using interpolation.
• Filtered blocks are generated using the filtered pixel values.
• A decoded video sequence is generated based on the filtered blocks.

Potential Applications

This technology could be applied in video decoding software, streaming services, and video editing tools.

Problems Solved

This technology helps improve the quality of decoded video sequences by reducing artifacts at block boundaries.

Benefits

The method enhances the visual quality of decoded videos and provides a smoother transition between adjacent blocks.

Potential Commercial Applications

"Enhancing Video Decoding Quality with Interpolation and Filtering" could be used in video streaming platforms, video editing software, and multimedia devices.

Possible Prior Art

One possible prior art could be the use of interpolation techniques in image processing to improve image quality.

How does this method compare to other video decoding techniques in terms of computational efficiency?

This article does not provide information on the computational efficiency of this method compared to other video decoding techniques. It would be interesting to know if this approach requires more computational resources or if it is more efficient than existing methods.

Are there any limitations to the size or resolution of the encoded video sequences that can be decoded using this method?

The abstract does not mention any limitations regarding the size or resolution of the encoded video sequences that can be decoded using this method. It would be important to understand if there are any restrictions on the types of videos that can be processed with this technique.

Original Abstract Submitted

an encoded video sequence including a plurality of images may be decoded. first and second adjacent blocks of an image of an encoded video sequence may be provided. a line of pixels including pixels of the first and second blocks may be defined extending across a boundary between the first and second blocks. a first reference value may be calculated based on a first pixel of the pixels from the first block. a second reference value may be calculated based on a second pixel of the pixels from the second block. filtered pixel values for each pixel of the line of pixels between the first pixel and the second pixel may be calculated using interpolation based on the first and/or second reference values. filtered blocks may be generated using the filtered pixel values, and a decoded video sequence may be generated based on the filtered blocks.
