<title>Color change method for objects in images</title>

Abstract

The color change method we developed uses a reflection model on the object's surface and constructs a new color mixture model for the object-background boundary to help preserve the natural appearance of the objects involved. The reflection model is based on object color, illumination, and surface reflection. While the object color can be changed while preserving the reflection, however, a problem occurs that makes the boundary color appear discontinuous and the object edge overly prominent. When images are digitized, light from the object and the background mix at the boundary, so the object merges naturally into the background. To solve the problem and preserve the naturalness as the original, we propose a boundary-color mixture model that maintains the color blending ratio of the original image and avoids color- related changes in the boundary smoothness.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
