Automatic Selection of Color Channels for Segmentation of Aerial Images with Photometric Variations

The choice of a color model is of great importance for aerial image segmentation algorithms. However, there are many color models available; the inherent difficulty is how to automatically select a single color model or, alternatively, a subset of features from several color models producing the best result for a particular task. To achieve proper colors components selection, in this paper, it was proposed the use of wrapper method, a data mining approach, to perform the segmentation process. The result yields good feature discrimination. The method was verified experimentally with 108 images from Amsterdam Library of Objects Images (ALOI) and 97 aerial images with different photometric conditions. Furthermore, it has shown that the color model selection scheme provides repeatability and distinctiveness for aerial segmentation.
