Methods and apparatuses for image enhancement

摘要

Embodiments of a method and apparatus for image enhancement are generally described herein. In some embodiments, the method includes accessing two or more sets of first pixel data representative of two or more images of a physical object. The method can further include transforming the two or more sets of pixel data to generate two or more sets of frequency domain data. The method can further include upsampling each of the two or more sets of frequency domain data to generate a set of upsampled frequency domain data. The method can further include re-transforming the set of upsampled frequency domain data to generate two or more sets of second pixel data. The method can further include combining two or more sets of second pixel data to generate an enhanced image of the physical object. Other example methods, systems, and apparatuses are described.

1. A method of image enhancement, comprising:
accessing first pixel data representative of a first image, the first pixel data including a number of pixels and the first pixel data being represented in a first domain, the first pixel data having a first array dimension corresponding to the number of pixels; conditioning first pixel data for edge refinement to generate edge-enhanced image data; transforming the edge-enhanced image data from the first domain into a second domain different from the first domain to generate transformed image data; upsampling the transformed image data based on an upsampling ratio to generate upsampled data; and transforming the upsampled data into the first domain to generate second pixel data, the second pixel data having a second array dimension greater than the first array dimension, the second array dimension corresponding to the upsampling ratio.
