## Abstract

a device configured to emulate a foveal mechanism in a correlithm object processing system comprises a memory and one or more processors. The memory stores a correlithm object mapping table that includes multiple source image elements and multiple corresponding target correlithm objects. The processors receive an image having a bitmap format and identify a first focus block of the image that includes multiple sub-blocks. The processors then compute a composite score for the first focus block that indicates a matching level between the first focus block and the source image. The processors then identify a direction to move the first focus block to a second focus block. The processors then compute a second composite score for the second focus block with respect to the source image and compare the second composite score to the first composite score to determine whether the matching level improves.
