Resolution Enhancement of Discrete Optical Sensors.
Abstract
The approach to the solution of the problem followed in this research has been to trade incremental motion of the sensor array or image and gray level information for increased resolution of black and white (two-level) images. Many techniques have been proposed for resolution enhancement by improving images corrupted by additive noise. However, a technique developed jointly by one of the authors makes it possible to resolve bits of information in the image space which are smaller in area than the area of the sensors in the array. The technique developed is an extension of the above technique which eliminates the requirement for known boundary conditions, and it extends the applicability to a more general class of problems. This enhancement technique is naturally divided into three functional areas. The first is a novel sensing arrangement first proposed by McRee and one of the authors. The second natural division of the process is the quantization of the samples. The third natural division of the process is the estimation of the state of the resolution elements based upon the quantized values of the samples and upon the known sample positions.
