Image Processing Device and Method For Performing Quality Optimized Deblocking - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240107077 titled 'Image Processing Device and Method For Performing Quality Optimized Deblocking
Simplified Explanation
The abstract describes an image processing device for deblocking block edges in an image encoded with a block code. The device includes a filter that filters the block edge by determining filtered pixel values based on original pixel values and clipping values, resulting in deblocked pixel values.
- The image processing device includes a filter for deblocking block edges in encoded images.
- The filter determines filtered pixel values based on original pixel values and at least one further pixel value.
- Clipping values are determined based on the distance of the pixel from the block edge.
- The filtered pixel values are clipped using the clipping values to produce deblocked pixel values.
Potential Applications
This technology can be applied in image and video compression systems to improve the visual quality of encoded images by reducing blocky artifacts.
Problems Solved
This technology addresses the issue of blocky artifacts that can occur at block edges in compressed images, leading to improved visual quality and overall user experience.
Benefits

Original Abstract Submitted
an image processing device for use in an image encoder and/or an image decoder, for deblocking a block edge between a first block and a second block of an image encoded with a block code, is provided. the image processing device comprises a filter for filtering the block edge, configured to, for at least some of the pixels to be filtered, within a deblocking range from the block edge, the deblocking range being perpendicular to the block edge, determine a filtered pixel value from an original pixel value of the pixel and at least one further pixel value, determine a clipping value of the pixel, dependent upon a distance of the pixel from the block edge, and clip the filtered pixel value, using the clipping value resulting in a deblocked pixel value.
