Abstract:

In opto-electronic imaging systems, aliasing will occur when sampling a scene containing spatial frequencies exceeding one half of the sampling frequency. A novel superresolution technique, micro zooming, is proposed, which can reduce aliasing and improve the resolution of the imaging systems through a series of aliased frames with different optical magnifications. Both computer simulations and experimental results are presented to verify the effectiveness and simplicity of micro-zooming technique for obtaining superresolution.
