Abstract
A method and system for high-speed and low-complexity geometric transformation of signals are described. In one embodiment, the system comprises an input patch consisting of a window of pixels from an input image. The system may further comprise a transformation selector to generate control data to control a geometric transformation mapping based on the location of a current pixel being processed. In one embodiment, the system may also comprise a hardware geometric transform engine to perform a geometric transformation mapping by switching on one path through the geometric transform engine from an input window to an output pixel using the control data. In one embodiment, the system may further comprise an interpolator to generate interpolated geometric transformation mappings using the control data and multiple outputs from the geometric transform engine by switching on multiple paths from an input window.
