The algorithm model should be capable of receiving an image (input data) of a document and returning a picture of the same dimension with the background in black pixels and the region of the document in white pixels.

Task 1

Reference paper:

A Fast Fully Octave Convolutional Neural Network for Document Image Segmentation


Database division:
Statistics from the dataset and experimental partition used in the Train and Test, where C1, C2, and C3 correspond to the 1st, 2nd, and 3rd Tasks, respectively.

To evaluate the methods, the following similarity metrics will be considered:

Dice Similarity Coefficient (DSC);
Scale Invariant Feature Transform (SIFT);
