==SCENE CHANGE DETECTION WITH NOVEL VIEW SYNTHESIS==


This abstract first appeared for US patent application 20250014290 titled 'SCENE CHANGE DETECTION WITH NOVEL VIEW SYNTHESIS

==Original Abstract Submitted==

a method for detecting changes in a scene includes accessing a first set of images and corresponding pose data in a first coordinate system associated with a first user session of an augmented reality (ar) device and accessing a second set of images and corresponding pose data in a second coordinate system associated with a second user session. the method identifies the first set of images corresponding to a second image from the second set of images based on the pose data of the first set of images being determined spatially closest to the pose data of the second image after aligning the first coordinate system and the second coordinate system. a trained neural network generates a synthesized image from the first set of images. features of the second image are subtracted from features of the synthesized image. area of changes are identified based on the subtracted features.
