REFERENCE IMAGE SLICING

摘要

Method and systems for generating reference features sets for slices of a reference image. The reference features sets generated from slices enables better object recognition and/or tracking when a camera image only shows a portion of the reference image. Metadata is used to link the reference features set of the original image and of the slices together as belonging to the same object, providing hierarchical relationship information and/or spatial relationship information. An image processing function may be dynamically configured on the basis of whether an object has been successfully detected and the metadata associated with the object.

主权项

1. A method of generating reference features sets on the basis of a reference image of an object, said reference features sets for use in an image processing function configured to recognize the object and/or estimate pose information of the object from an image frame obtained from a digital imaging device by matching extracted features of the image frame with the reference features sets, the method comprising:
extracting a first reference features set from the reference image; obtaining a first slice of the reference image, wherein the first slice is a first portion of the reference image; and extracting a second reference features set on the basis of the first slice.
