  • Publication number: 20240144591
    Abstract: A method for generating a virtual scene comprising one or more 3D objects is provided. The method includes creating a 3D model of a real world 3D scene, capturing an image of the real world 3D scene by a physical camera to obtain a captured image, creating a digital camera model of the physical camera, rendering a virtual 3D scene comprising virtual 3D objects based on the digital camera model using physical-based rendering software to obtain a virtual image, and minimizing dissimilarity norm between the captured image and the virtual image to optimize positions and surface parameters of the virtual 3D objects in the virtual 3D scene.

  • Patent number: 11481873
    Abstract: An image processing method is provided The image processing includes images obtained using a Red-Clear-Clear-Blue (RCCB) color filter array. An image processing method for processing an RCCB image obtained by an image capturing device comprising an array of photosensors with a mosaic of RCCB filters comprises interpolating the RCCB image to obtain dense C-channel data from a sparse C-channel, and chromatic filtering, based on the RCCB image data and the dense C-channel, to obtain an RGB image by obtaining the dense R-channel and B-channel, and filtering the R-channel and B-channel using the guide image. The computational load on the image processing equipment and the processing time are reduced, while enhancing the obtained image quality, including in low light conditions.

  • Patent number: 11238302
    Abstract: A method and an illumination manipulation device of performing an object illumination manipulation operation on a first image are provided. The method includes receiving the first image and an input of a light direction, generating a second image with a first object detected from the first image, determining a second object illumination of the second image based on the light direction and replacing a first object illumination of the first image with the second object illumination.

  • Publication number: 20220005160
    Abstract: An image processing device includes an encoder configured to receive a blurry image and generate a global feature map of the image, a merging unit configured to merge the global feature map and blur information, a decoder configured to generate a feature tensor and weight tensors, a recurrent refinement module configured to perform recurrent feature filtering, and an image reconstruction module configured to reconstruct a deblurred image where the image processing device is configured to estimate an image global shift and to activate or deactivate the recurrent refinement module based on the estimation.
