Abstract: Proposed in various embodiments of the present disclosure are a device and a method for image processing, whereby image conversion by dilation is carried out in a multimedia system. To this end, an electronic device for image processing may identify between a first unused area in a first picture and a second unused area in a second picture, the first unused area and the second unused area having the same time information. The electronic device may acquire fill values for replacing the first unused area and the second unused area, on the basis of a value acquired from the first unused area and a value acquired from the second unused area. The electronic device may acquire a first converted picture and a second converted picture by replacing the first unused area and the second unused area by using the acquired fill values.

Abstract: Provided is a method of processing and transmitting three-dimensional data represented as a point cloud.
The method of encoding three-dimensional (3D) data includes: generating a geometry image indicating position information of points, a texture image indicating color information of the points, and an occupancy map indicating occupancy information of the position information of the points in the geometry image, by projecting the points included in the 3D data onto a two-dimensional (2D) plane; generating a filtered occupancy map by performing filtering on the occupancy map; performing image padding on the geometry image and the texture image, based on the filtered occupancy map; and generating and outputting a bitstream including a padded geometry image, a padded texture image, a downsampled occupancy map, and information about the filtering performed on the occupancy map.-
