TEMPORAL FILTERING WEIGHT COMPUTATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18211376 Titled 'TEMPORAL FILTERING WEIGHT COMPUTATION'
Simplified Explanation
The abstract describes a technique for filtering images based on their timestamps. The technique involves acquiring two images taken at different times, performing a motion compensation operation on the first image, and generating a difference image that shows the intensity differences between the two images. A local weight map is created based on these differences, and a global weight map is generated using certain IMU data. These weight maps are combined to create a final weight map, which is then used to filter the images and generate a filtered image.
Original Abstract Submitted
Techniques to temporally filter images via a filtering weight computation are disclosed. A first image having a first timestamp and a second image having a second timestamp are acquired. These images are generated by a camera, and the first timestamp is before the second timestamp. A motion compensation (MC) operation is performed on the first image to produce an MC image. A difference image is generated using the MC image and the second image. The difference image reflects differences in intensities that exist between the two images. A local weight map is generated based on those differences. A global weight map is generated based on certain IMU data. A final weight map is generated based on a combination of the local weight map and the global weight map. The final weight map is used to generate a filtered image.
