Abstract
The present application relates to a method and device for extracting information from a histogram for display on an electronic device. The method comprises the following steps: inputting, into the electronic device, a document, which includes a histogram to be processed; detecting each element in the histogram to be processed by using a target detection method based on a Faster R-CNN model pre-stored in the electronic device; performing text recognition on each detected text element box by the electronic device; to extract corresponding text information; and converting all the detected elements and text information into structured data for display on the electronic device. The method and the device can detect all the elements in the histogram through deep learning and the use of the Faster R-CNN model for target detection, thus providing a simple and effective solution for information extraction in the histogram.
