and DR surgery and advanced treatments in the
third level (see Figure 2).
Table 1 presents the details about how we create
several data sets namely d1-d6. Please note that the
use of different data sets makes the models more
robust for a variety of images and try to avoid problems related to the bias of the data set.
Methods
The management of the use case was inspired by an
agile data science methodology known as team data
science process (TDSP), which provides a life cycle of
this project. Besides, we used a version control system
(VCS) known as GitLab as a tool chain to collaborate,
integrate, manage, configure, maintain, and document
all activities and codes associated with the project. We
split the project into seven main stages:
* project setup and a draft of the ethical board
review,
* problem understanding,
* experimental setup,
* data acquisition and labeling,
* data exploration/modeling,
* model evaluation,
* deployment.
In this work, we only present the modeling and
evaluation stages. Our data preparation includes the
creation of the data sets with a hold-out split strategy. The training of the models was done by using
the Unet [68] (mO-segmentation or cropping [69])
