Method and apparatus for detecting changes in an enviroment

Abstract

A method for detecting changes in a physical environment is provided. The method is performed by an apparatus. The method includes obtaining a first image representing the physical environment at a first time instance, and obtaining a second image representing the physical environment at a second time instance. The method further includes using the second image as input to a set of machine learning, ML, models to generate a reconstructed image of the second image from each of the set of ML model, and selecting an ML model among the set of ML models with a smallest reconstruction error between the second image and the generated reconstructed image of the second image. The method further includes detecting if there are changes in the physical environment by using the first image and the second image as input to the selected ML model.
