基于HSL空间的彩色形态变换

Color Morphological Transforms Based on HSL Space

彩色形态变换是数学形态学从灰度图象到彩色图象的推广。该文基于HSL(hue-saturation-lightness)彩色空间,提出了彩色形态变换理论,定义了新的彩色形态算子,并讨论了它们的性质。彩色形态变换作为一种数学形态学方法在彩色空间的延拓,可有效地应用于图象处理、图象编码和目标形状特征提取等。

Based on HSL (hue-saturation-lightness) color space, a new approach to color morphology, an evolution of mathematical morphology from gray-scale image to color image, is proposed . New color morphological operators are defined, and their properties are discussed. As an extension of mathematical morphology to color space, the proposed transformation can be efficiently used in color image processing, image encoding and shape features extraction of objects, etc.
