IMAGE RESAMPLING WITH GEOMETRIC TRANSFORMATION

摘要

Embodiments of the present invention provide systems, methods, and computer storage media directed at image resampling with geometric transformation. In embodiments the method may begin by determining a two-dimensional filter for application to an original image to produce a resampled image. This determining may be based on a specified geometric transformation. The method can proceed by computing identifiers for pixel locations in the resampled image that indicate a position of the two-dimensional filter with respect to the original image. Additionally, the method can include applying the two-dimensional filter to the original image in accordance with the computed identifiers to produce the resampled image. Other embodiments may be described and/or claimed.
