摘要: Inner and outer hexoctahedrons respectively showing complete background are defined by combining triangular pyramids centered on a representative color RGB space. Key value is calculated changing identification function parameters depending upon which of constituting the hexoctahedron each pixel image belongs to. As result, an improved foreground for composite obtained.
