Plot2Spectra: an automatic spectra extraction tool Extensive experiments are conducted to validate the effectiveness of the proposed plot digitizer, which could help accelerate the discovery and machine learning of materials properties. DigitizeIt makes it easy to actually get back numbers from such a plot This is a three step process: import the graph from a file or copy it. in most scientific publications only plots but no data values are published. Sometimes it is necessary to extract data values from graphs, e.g. In the second, the plot data extraction stage, we first employ semantic segmentation to separate pixels belonging to plot lines from the background, and from there, incorporate optical flow constraints to the plot line pixels to assign them to the appropriate line (data instance) they encode. DigitizeIt digitizer software replaces a digitizer tablet. We also apply scene text detector to extract and interpret all tick information below the x-axis. In the first, the axis alignment stage, we adopt an anchor-free detector to detect the plot region and then refine the detected bounding boxes with an edge-based constraint to locate the position of two axes. The main features of this plot digitizer are: Support a wide range of charts (XY, bar, polar, ternary, maps etc. Specifically, the plot digitizer is a two-stage framework. In this paper, we develop a plot digitizer, named Plot2Spectra, to extract data points from spectroscopy graph images in an automatic fashion, which makes it possible for large scale data acquisition and analysis. However, such graphs are not conducive to direct programmatic analysis due to the lack of automatic tools. In this guideline, we describe our experience in the application of two software to extract data from graphs, including Plot Digitizer and Getdata Graph. In scientific literature, XANES/Raman data are usually plotted in line graphs, which is a visually appropriate way to represent the information when the end-user is a human reader. Different types of spectroscopies, such as X-ray absorption near edge structure (XANES) and Raman spectroscopy, play a very important role in analyzing the characteristics of different materials.
