| In this paper, a method of specific colored area extraction into a color image is presented. Usual color segmentation or edge de- tection operators perform a global processing on the image. Thus, every area into an image is detected. The whole image is subdi- vided into several region by labeled pixels, or boundaries in case of an edge detection. Our purpose is to extract only specific areas into an image sharing a specific color attribute, hence sharing a common color based on a specific hue. The quaternionic geometrical transfor- mation into RGB color space is used. A specific hue axis is defined. From this axis, a criterion defines a color subspace into an RGB color space using the quaternionic HSI interpretation of RGB vectors. |
