Abstract
Methods for generating and implementing digital orientational filters. A first method of the present invention is provided for generating digital orientational filters of uniform size but each having a different fixed orientation. A second method provides for dilation of the digital orientation filters generated by the first method, both in a decimated and an undecimated format. A third method of the present invention provides for steering the orientation of the filters generated by the first method. Also, associated VLSI hardware based systems implementing the above methods are disclosed. The above methods and systems allow digital orientational filters to be utilized in computer vision and other applications requiring a large amount of video signal data to be processed in real-time.
