摘要

A new passive method for improving the contour resolution of a moving object and overcoming the diffraction limit without having any a priori information is presented. The resolution improvement is obtained using a sequence of low-resolution images taken at different positions of an unknown object moving in respect to an unknown background. The super resolving process has two steps. First, a high-resolution estimation of the background is reconstructed using a deconvolution algorithm. Second, the captured set of low-resolution images is decoded by the deconvolved background, and a high-resolution image of the object's contour is generated.
