* Ramzi: tested end-to-end model with learning
 +
** missing one step, results expected next week
 +
* Yasmine + Yichen: working on pre-processing
 +
** Testing cylinders distortions -> flat rectangle
 +
*** open cv
 +
*** Tesseract performance very poor
 +
 +
Next week:
 +
* 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
