IMAGE PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18558741 titled 'IMAGE PROCESSING METHOD
The image processing method described in the patent application involves obtaining a current image frame and a reference image frame, performing downsampling and upsampling on both frames, dividing them into sub-blocks, determining matching blocks, obtaining motion vectors, and encoding the current image frame based on the motion vectors.
- Downsampling and upsampling are sequentially performed on the current and reference image frames.
- The processed frames are divided into sub-blocks according to a preset division manner.
- Matching blocks are determined by finding the reference image sub-block with the minimum similarity to each current image sub-block.
- Motion vectors corresponding to each current image sub-block are obtained based on the matching blocks.
- The current image frame is encoded using the motion vectors.
Potential Applications: - Video compression technologies - Image recognition systems - Surveillance systems - Virtual reality applications
Problems Solved: - Efficient encoding of video frames - Improved motion estimation accuracy - Reduced data storage requirements
Benefits: - Enhanced video quality - Reduced bandwidth usage - Faster video processing speeds
Commercial Applications: Title: Video Compression Technology for Enhanced Quality and Efficiency This technology can be utilized in video streaming services, security cameras, video editing software, and virtual reality applications to improve video quality and reduce data storage requirements.
Questions about Image Processing Method: 1. How does the method of downsampling and upsampling contribute to the efficiency of the image processing? 2. What are the key advantages of using motion vectors in encoding the current image frame?
Original Abstract Submitted
An image processing method includes: obtaining a current image frame and a reference image frame; sequentially performing downsampling and upsampling on the current image frame to obtain a processed current image frame, and sequentially performing downsampling and upsampling on the reference image frame to obtain a processed reference image frame; according to a preset division manner, dividing the processed current image frame into current image sub-blocks and dividing the processed reference image frame into reference image sub-blocks; determining a reference image sub-block with a minimum similarity to each current image sub-block among the reference image sub-blocks as a matching block of the current image sub-block; obtaining a motion vector corresponding to the current image sub-block based on each current image sub-block and the matching block corresponding to the current image sub-block; and encoding the current image frame based on the motion vector.
