Abstract
The apparatus and method of the present invention provides a process that can be implemented by a human operator and a computing device to analyze and display human skin images. The system acquires a digital image from a camera or scanner. Subsequently, the system determines which area(s) of the image to analyze using landmarks such as the corner of the eye. The determined areas are then analyzed to locate skin defects such as red spots, and the defects are visually identified on a display. A severity is calculated for the defects and the severity is compared to an average skin severity associated with a population of people. In addition, a simulation is generated and displayed showing an improvement to the defect areas.
