Abstract
Disclosed embodiments relate to a systems and methods of identifying a target object in an image using image processing. Template data is stored which represents a template orientation field indicative of an orientation of each of a plurality of features of a template object. Image data may be received and processed to generate an image orientation field indicating an orientation corresponding to the plurality of image features. The image data may be further processed to generate image confidence data based on at least one characteristic for use in identifying the target object in a given image, and the characteristic may be indicative of an increased likelihood that at least one part of the given image represents at least part of the target object, relative to other parts of the given image. The image orientation field is processed using the template orientation field and the image confidence data to generate a match metric indicative of an extent of matching between at least part of the template orientation field and at least part of the image orientation field. The match metric may then be used to determine whether or not the target object has been identified in the image.
