half-face color image

Quick answer：

A half-face color image refers to a photograph or digital image that captures only half of a person's face, typically from the front. This can be done for artistic purposes, as a way to focus on a specific feature or expression, or for medical reasons, such as in facial recognition or in depicting specific facial conditions. The image is likely to be two-dimensional and may be cropped or manipulated to emphasize the half-face aspect.
