Patent Images
1. A method of classifying an object in an image, comprising:
- providing a plurality of sub-classifiers, the plurality of sub-classifiers comprising image-based classifiers and depth based classifiers, the image-based classifiers comprising one of a contour-based classifier and an edge-based classifier, the image-based classifiers identifying elements based on at least one image, the depth-based classifiers identifying elements based on depth relative to one of a sensor and at least one reference point, the contour-based classifiers identifying elements based on properties derived from significant intensity transitions of similar quality in an image along continuous long segments or curves, the edge-based classifiers identifying elements based on properties derived from significant intensity transitions of similar quality in an image along short, straight, continuous segments; and
classifying the object using input from each of the plurality of sub-classifiers.
