Abstract

The invention pertains to a method (100) for creating a texture from input images, thereby removing representations of objects from the texture, the method comprising performing semantic segmentation (120) in a plurality of digital input images with a plurality of semantic classes, at least one of the semantic classes relating to a target object class; identifying (140), in at least a first input image, one or more possible instances of representations of objects belonging to the target object class, each possible instance being constituted by a plurality of contiguous instance pixels of the image pixels; determining whether the instance pixels are target pixels, target pixels being pixels constituting a representation of an object belonging to the target object class; and replacing (190) target pixels in the texture with replacement pixels derived from one or more of the plurality of digital input images, wherein determining whether the instance pixels are target pixels comprises: using a structure-from-motion algorithm and the known positions and orientations to combine (130) the individually segmented input images into a single 3D model; mapping (150) the instance pixels to the common coordinate system; projecting (160) the mapped instance pixels to the other input images; and determining (170), based on the segmentation of a plurality of input images, whether the mapped instance pixels constitute a representation of an object belonging to the target object class.
