Abstract
System and techniques for a visual vehicle parking occupancy sensor are described herein. A color image, including a parking space, is received from a camera. A cascaded search for vehicle features in a hue-saturation-value (HSV) converted version of the color image is performed to produce search results. A search for macro vehicle features in the color image is also performed to produce an indication of found macro vehicle features when the search results are of a first type. An occupancy indicator is provided based on the search results when the search results are of a second type and based on the indication otherwise.
