Wahyu Pratomo, Hertog Nugroho · 2013
Graph Feature Extraction is the task to collect any important feature on the graph image so the extracted data can be further processed. In this paper, it is assumed that the graph consists only one single curve. The extracted features here are graph title, axis title, axis values, legend, scales, and curve values.
