  • Method and apparatus for stitching images
    Patent number: 11875490
    Abstract: An image stitching method and apparatus are disclosed. The image stitching apparatus includes at least one processor and a memory. The processor may obtain a plurality of images at different viewpoints, estimate homographies of each of the plurality of images, generate an aligned image by aligning the plurality of images based on the homographies of each of the plurality of images, obtain a collective energy map by inputting the aligned image to a neural network, estimate a stitching line of the aligned image based on the collective energy map, and generate a stitched image by blending the aligned image based on the stitching line.
    Type: Grant

  • Raw sensor image and video de-hazing and atmospheric light analysis methods and systems
    Patent number: 9870600
    Abstract: A method for processing image or video data receives color filtered mosaiced raw image or video data. The method, performed in an image processing pipeline, de-hazes the color filtered mosaiced raw image or video data, e.g. Bayer image data, to create de-hazed mosaiced image or video data and de-mosaicing the de-hazed mosaiced image or video data to crate de-hazed and de-mosaiced image or video data.
