Performing distance-based feature suppression

An automobile driver-assistance system comprising:

• an interface operable to receive an image from an image capture device;
• at least one processor coupled to the interface;
• and
• a non-transitory memory coupled to the at least one processor and that stores instructions that, when executed, cause the at least one processor to:
• receive a list of features of the image, wherein each feature of the list of features has a respective measure of a property;
• select a first feature of the list of features;
• identify a subset of features of the list of features that are located within a distance of the first feature;
• determine from among the first feature and the subset of features, a second feature having a respective measure of the property that is greater than a remainder of the first feature and the subset of features;
• mark the second feature as valid;
• and
• mark the remainder of the first feature and the subset of features as suppressed.
