  • Abstract
    The problem of increasing the resolution of discrete optical sensors in information systems is considered. The proposed method uses an overlapping scan and multilevel quantization. The samples thus obtained are processed by a minimum mean square estimator utilizing the pseudoinverse of the transformation matrix. The method is illustrated by a 4/1 enhancement of an 8 × 8 resolution grid. Experimental results are presented.
