Abstract: An imaging apparatus generates a 3D model using a photographed image of a subject and generates a 3D image based on the 3D model. When a corresponding point corresponding to a point forming the 3D model does not form a 3D model generated using a photographed image photographed at a different photographing position, the imaging apparatus determines that the point is noise, and removes the point determined as noise from the 3D model. The imaging apparatus generates a 3D image based on the 3D model from which the point determined as noise is removed.

Abstract: A method, system and apparatus for adaptive pre-filtering includes: extracting tuning parameters from video data in a video encoding process; processing the tuning parameters to generate control parameters representative of properties of the video data; coupling the control parameters to a filter response; generating filter coefficients according to the filter response; and filtering the video data using the filter coefficients prior to video encoding. The filtering of video data may thus be adapted to one or more tuning parameters of the video data and the encoding process. The filtering may decrease the complexity of encoding by an attenuation of high frequency signals, effectively decreasing the quantization step and reducing compression artifacts.

Abstract: Described are techniques in video coding and/or decoding that allow for selectively breaking prediction and/or in loop filtering across segment boundaries between different segments of a video picture. A high layer syntax element, such as a parameter set or a slice header, may contain one or more indications signalling to an encoder and/or decoder whether an associated prediction or loop filtering tool may be applied across the segment boundary. In response to such one or more indications, the encoder and/or decoder may then control the prediction or loop filtering tool accordingly.
