Claim One:
1. A method for detecting objects in a video sequence of image frames, comprising: for a first frame, detecting objects by: employing a processor for searching a region in a first frame for a desired object using a sliding window during a processing period, wherein a ratio of the size of the sliding window to the size of the first frame comprises a first size ratio; obtaining measurements in the sliding window based on object definitions; comparing the measurements with pre-defined values for the desired object to determine if the current windowed region includes the desired object; for a second frame, detecting objects by: employing a processor for searching a region in a second frame for a desired object using the sliding window during a processing period, wherein a ratio of the size of the sliding window to the size of the second frame comprises a second size ratio; obtaining measurements in the sliding window based on object definitions; comparing the measurements with pre-defined values for the desired object to determine if the current windowed region includes the desired object; and, wherein the first size ratio differs from the second size ratio.
