Abstract: To examine the charts critically and to synthesize the charts across relevant papers in a large-scale accessible digitally, we need an efficient way to extract data from visual information in the charts. Axis detection is the crux in such data extraction from the charts. Thus, we introduce a rule-based axis detection algorithm that is computationally less expensive and more accurate by using simple pixel counting.
