Abstract
A method for detecting a clear path of travel for a vehicle utilizing an image generated by a camera device located upon the vehicle includes monitoring the image, and generating a plurality of patches onto the image, wherein the patches are collectively arranged to substantially include the clear path of travel. Feature extraction is utilized to analyze the patches and includes convolving each of the patches with a feature detection filter generating a feature-based filter response, extracting features based upon the feature-based filter response, and determining each of the patches to represent the clear path of travel or to not represent the clear path of travel based upon the extracted features. The clear path of travel is determined based upon the plurality of patches, and is utilized to navigate the vehicle.
