+        This app leverages the machine learning engine built by Xuebin Qin ([https://github.com/xuebinqin/DIS](https://github.com/xuebinqin/DIS)) to mask the prominent subject within a photograph.
         The mask is used to keep the subject in clear focus while an adjustable slider is available to interactively blur the background.
         To use, upload a photo and press the run button. You can adjust the level of blur through the slider and view the mask using the "Show Generated Mask" button.
