Image Reconstruction from Multiple Frames of Data

Abstract. High-resolution image reconstruction from sparse data is an important problem in sensor array imag-ing (SAI). The reconstructed images from such a data re poorly resolved. However, there may exist possibilities of making multiple measurements, for example, collecting many frames of data in a dynamic scene situation where there is relative motion between the object and the receiver. We discuss here a method of reconstructing good-quality images from multiple frames of sparse data obtained from a simulated dynamic scene situation. This method, based on projection onto convex sets (POCS), not only restricts the solution set by satisfying the constraints in the multiple measurements butalso reconstructs a high-resolution image
