Abstract:
A method for generating a high-resolution image having an array of proportionally spaced high-resolution grid points derived from multiple low resolution images each having an array of low resolution pixels, comprising:deriving motion vectors that each originate from the proportionally spaced high-resolution grid points in the high-resolution image, the motion vectors each associated with one of the multiple low resolution images;associating the high-resolution grid points with inter-pixel positions on the associated low-resolution images using the motion vectors;identifying one or more of the low-resolution pixels on each one of the low-resolution images having the closest spatial distance to the inter-pixel positions;selecting one or more of the identified low-resolution pixels for each one of the high-resolution grid points having a shortest distance; andmapping pixel intensity values into the high-resolution grid points according to the selected low-resolution pixels.
