1. An image enhancement system for enhancing a two-dimensional display image, the image enhancement system comprising:
image processing circuitry configured to perform operations, the operations comprising:
receiving an image signal that represents a two-dimensional camera image of a surface of an anatomical target being illuminated by light having a first pattern of lines;
detecting, from the two-dimensional camera image, a second pattern of lines, the second pattern of lines including at least some lines that are distorted in at least one of spacing or thickness compared to the first pattern of lines;
determining contour information of the surface of the anatomical target based on the distortion of the second pattern of lines compared to the first pattern of lines; and
generating an enhanced two-dimensional image that includes the two-dimensional camera image with adjusted shading based on the contour information.
