Abstract
The disclosed subject matter includes an apparatus configured to remove a shading effect from an image. The apparatus can include one or more interfaces configured to provide communication with an imaging module that is configured to capture the image, and a processor, in communication with the one or more interfaces, configured to run a module stored in memory. The module is configured to receive the image captured by the imaging module under a first lighting spectrum, receive a per-unit correction mesh for adjusting images captured by the imaging module under a second lighting spectrum, determine a correction mesh for the image captured under the first lighting spectrum based on the per-unit correction mesh for the second lighting spectrum, and operate the correction mesh on the image to remove the shading effect from the image.
