Image Segmentation

I need a project on image segmentation. The dataset is given and a sample code implemented using U-net is given. The task is to implement two models other than U-net. I need at least one model in 12 hours. Apologies for the late request but the person I contacted earlier promised to do but isn't responding now. I am unable to upload the files related to the project as they are large. If someone can contact me I can send them. Thank you in advance.
