Abstract
In an image processing method for a driver assistance system for detecting and classifying a portion of a predefined image element having a road sign in a digital image captured by an image sensor of the driver assistance system, first scale-invariant image features and their relative geometric arrangement with respect to one another are computed based on at least one image region of the digital image to be searched, after which a classifier compares the first scale-invariant image features and their relative geometric arrangement with respect to one another to stored and/or learned second scale-invariant image features and their relative geometric arrangement with respect to one another which are computed based on the at least one predefined image element.
