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.

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.

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.
