说明：  图片形态学app拥有一个交互式开发环境，利用它可以对图片进行多种形态算法操作，很好用。
(The Image Morphology app is an interactive exploratory environment, with which you can try different morphological operations and structuring elements on your image. This app supports most morphological operations, including those (like BWHITMISS) that can take multiple STRELS. All STRELS, including arbitrary ones, are now supported. You can easily see the effects of changing the size or shape of your STREL, or of trying different morphological operations. You can also activate the modified image to string operations. )
