Abstract: For an image processing concept, a database including data derived from a plurality of frames of a video is provided in a device. A live video feed is obtained from a camera of the device. Information is extracted from an image of the video feed. A search is performed in the database using the extracted information to retrieve a list of potential frames out of the plurality of frames. An initial pose of the selected image is estimated with respect to one frame of the list as a function of the extracted information and the data derived from the one frame. Respective subsequent poses for subsequent images from the live video feed are iteratively estimated, wherein the associated subsequent pose is estimated based on said subsequent image and a respective previously estimated pose. The video feed is augmented on the device with virtual information based on the estimated initial pose and the subsequent poses.
