    摘要: Methods and devices for encoding or decoding a point cloud. A bit sequence signalling an occupancy pattern for sub-volumes of a volume is coded using entropy coding. For a current sub-volume, probabilities of respective entropy coders for entropy coding the occupancy pattern may be selected based on occupancy data for a plurality of neighbouring sub-volumes of the current sub-volume and on occupancy data for subdivisions of the neighbouring sub-volumes.

    摘要: An example electronic device includes a camera, a communication module, and at least one processor. The at least one processor is configured to acquire a raw image of an external object by using the camera, generate a first corrected image from the raw image by a first image processing scheme, control transmitting the raw image to an external electronic device through the communication module in order to enable the external electronic device to generate differential image information corresponding to a difference between a second corrected image generated by processing the raw image in the first image processing scheme and a third corrected image generated by processing the raw image in a second image processing scheme, and further correct the first corrected image by using the differential image information so that the further corrected first corrected image corresponds to the third corrected image.

    摘要: An apparatus for building a map is disclosed. The apparatus for building a map according to the present invention includes a data collection unit configured to separately collect vector data and raster data, a vector data processing unit configured to generate ground-truth images of a previously set size by processing the vector data, a raster data processing unit configured to generate divided raster images of the set size by processing the raster data, and a polygon generation unit configured to generate predicted polygons through machine learning of the ground-truth images and the divided raster images and generate polygons which can be applied to map building based on the raster data on the basis of the predicted polygons and the ground-truth images.

    摘要: A method and device for modifying attributes of one or more points of a 3D scene, the attributes comprising depth attribute and texture attribute stored respectively in a depth image and a texture image. To reach that aim, at least a first point of the 3D scene is identified, the at least a first point having depth information inconsistent with regard to depth information associated with a neighborhood of the at least a first point in the depth image. It is then determined whether the attributes of the at least a first point are correctable by analyzing neighborhood of the at least a first point in the depth image and in the texture image. For each first point having correctable attributes, the attributes stored in the depth image and/or texture image are modified according to the neighborhood in the depth image and/or in the texture image.
