ABSTRACT:
An image processing method for inserting a given pattern at a target region having a particular location with respect to a scene being viewed by an image sensor over a period of time, wherein the method employs a world map having stored therein the relative position of the location and the pose of multiple pre-trained reference image patterns of landmark regions in the scene with respect to that of the target region. The method comprises dynamic computation steps for inferring the size and position of the particular location within each of ongoing successive image frames of the scene from the shape, size and position of at least one of said multiple landmark regions represented within each of successive image frames of the scene, despite inaccuracies in the parametric model estimation relating the current image with the pre-trained reference image and changes over time in the shape, size and position of the image patterns of the multiple landmark regions from those of the pre-trained reference image patterns of the landmark regions stored in the world map.
