Abstract :
The automatic method of information extraction from heatmaps based on OCR, image processing and image recognition techniques is proposed. It is composed of the sequence of steps. First, the heatmap area is separated from other elements of the heatmap image. Next, the key and axis are recognized. To produce quick answers for a user query, the heatmap is stored in the form of a tree. The method was tested on the basis of several diverse heatmaps. The results are promising.
