基于决策树分类的Photoshop水体选区制作

Producing Water Body Selected Area of Photoshop Based on Decision Tree

福建省有多景SPOT-5影像都涉及海域,在Photoshop中对影像进行调色时,水体需要进行单独调色,所以要制作海水选区。当影像质量较差时,水体选区通常需要手工完成,费时费力。通过决策树来提取水体的范围,并将提取结果作为调色时的选区,可以节省很多时间和工作量。

Several SPOT-5 scenes of Fujian Province contain some area of sea water body.When these images were adjusted color in Photoshop,selected area of water body should be made because water body was usually adjusted color separately.If the images had poor quality,selected area of water body must be produced manually.It＇s a time and labor wasting work.Decision tree was used to extract water bodies in this paper and the classification results can be used as selected areas in Photoshop after simple process.A lot of time and effort can be save when this method is adopted.
