In this paper, an image resolution enhancing technique is described. It is based on extracting 1-dimensional characteristic curves from subsequent frames and sub-pixel displacement values. Through sub-pixel mapping and adaptive interpolation, high-resolution image can be obtained from several lowresolution image frames. This 1-dimensional algorithm is simple and cost-effective, and can be easil...

In previous work [2] we considered the problem of image interpolation from an adaptive optimal recovery point of view. We showed how a training set S determines a quadratic signal class and how to use this signal class to perform image interpolation. In [2] the training set S was taken from the low resolution version of the image we were interpolating. In this paper we continue our discussion o...
