description="This is the baseline function that will be used to generate the database for a machine learning model I am working on called 'DistortionMl'! The goal of this model is to detect and then reverse image transformations that can be generated here!\nYou can read more about the project at [this repository link](https://github.com/nick-leland/DistortionML). The main function that I was working on is the 'Bulge'/'Volcano' function, I can't really guarantee that the others work as well!\nI have just added the first baseline ML model to detect if a distortion has taken place! It was only trained on mazes though ([Dataset Here](https://www.kaggle.com/datasets/nickleland/distorted-mazes)) so in order for it to detect a distortion you have to use one of the images provided in the examples! Feel free to mess around wtih other images in the meantime though!"
