| + | * Ramzi |
| + | ** finish test end-to-end model |
| + | ** increase size of data set to get significant results |
| + | * Yasmine + Yichen |
| + | ** Cylinder unwrapping (classic + deep learning models) |
| + | *** review litterature |
| + | *** create data set for Ramzi using paid API "perfect label" |
| + | ** table structure detection : associate bounding boxes to key value pairs |
| + | * All |
| + | ** Create test set with cylindric photos + unwrapped photos |
