Abstract: The present invention generally relates to an apparatus and a method for obtaining a registration error map representing a level of sharpness of an image. Many methods are known which allow determining the position of a camera with respect to an object, based on the knowledge of a 3D model of the object and the intrinsic parameters of the camera. However, regardless of the visual servoing technique used, there is no control in the image space and the object may get out of the camera field of view during servoing. It is proposed to obtain a registration error map relating to an image of the object of interest generated by computing an intersection of a re-focusing surface obtained from a 3D model of said object of interest and a focal stack based on acquired four-dimensional light-field data relating to said object of interest.

Abstract: In a context of varying ambient luminosity, a salient idea is to adjust an image by adapting the contrast of an image according to a level of ambient light. Enhancing the contrast is known to make a displayed object more distinguishable, with some impact on the overall image quality. Increasing a level of contrast enhancement as the ambient light increases, advantageously allows to preserve distinguishable displayed objects in high levels of ambient light, despite an overall loss of quality, less perceivable in high levels of ambient light.

Abstract: A particular implementation determines color palettes of images by extracting and decomposing color palettes based on the image color content. The decomposition can produce a dictionary matrix, an activation matrix, or both. The dictionary matrix can be used in recoloring an image, either directly or after storing. Another implementation selects a color palette to recolor an image by accessing metadata associated with the image and estimating a scene type based on the metadata and/or other information. Color palettes are retrieved from memory corresponding to the scene type of the image and are used for recoloring the image. Instructions for the implementation can be stored on a non-transitory computer readable medium such that the embodiments can be implemented by one or more processors.

Abstract: One general aspect for motion-based video tonal stabilization uses a keyframe and motion estimation techniques to determine the level of spatial correspondence between input images and the keyframe. When the level of spatial correspondence is high, tonal stabilization is performed through regression and power law tonal transformation to minimize the color differences between images caused by automatic camera parameters without a priori knowledge of the camera model. Tonal error accumulation is reduced by using long-term tonal propagation.
