Character Segmentation using TensorFlow

Overview

Character Segmentation

Segment characters and spaces in one text line,from this paper Chinese English mixed Character Segmentation as Semantic Segmentation

dependencies

tensorflow1.3,or 1.4

python3

differences from the paper

the paper set the label of the space to 1,others 0.But that is not hommizate,because the space between two characters is many pixes,the network is hard to distinguish which is 1,which is 0,even though it can work.Here we change to set the characters to 1,spaces to 0.

you can choose first make traing images and then use these maked images to train ,or training and making at the same time.all you need to do is change below codes in data_generator.py
