Non-linear resolution vision systems

The concept of a nonlinear resolution (NLR) vision system is introduced. Some basic problems in developing NLR vision systems are discussed. An NLR vision simulation system is also proposed. This proposed system resamples a digitized linear resolution image with a nonlinear sampling rate. An NLR vision system does not sense an image with a uniform resolution. Therefore, the sensed image is distorted according to a chosen nonlinear curve (or surface). If the curve (or surface) is controlled properly, an NLR vision system can not only provide good resolution and a large image window at the same time when the number of image pixels is a constant, but can also provide an invariant description of objects in an image
