Abstract

In this work, we present a segmentation algorithm for color images that uses the watershed algorithm to segment either the two-dimensional (2-D) or the three-dimensional (3-D) color histogram of an image. For compliance with the way humans perceive color, this segmentation has to take place in a perceptually uniform color space like the Luv space. To avoid oversegmentation, the watershed algorithm has to be applied to a smoothed histogram.

摘要

在这项工作中，我们提出了一种用于彩色图像的分割算法，该算法使用分水岭算法对图像的二维（2-D）或三维（3-D）彩色直方图进行分割。为了符合人类感知颜色的方式，这种分割必须在感知均匀的颜色空间中进行，如 Luv 空间。为了避免过度分割，必须将分水岭算法应用于平滑后的直方图。
