The method comprises receiving a digital image of a scatter plot; analyzing the received digital image for identifying a plurality of pixel sets, each pixel set being a group of adjacent pixels; analyzing the pixel sets in the received image or in a derivative of the received image for ...
PlotDigitizer v3 (dmg) Frequently Asked Questions Brief answers to some of the common questions asked by our users What is PlotDigitizer? PlotDigitizer is data extraction software that digitizes graph and plot images. Its inbuilt functionality allows users to quickly extract data from graphs, plots...
Synthetic data on a scatter plot that will be used for extraction. Image by the author. Also, it is important to remember that when we use data from sources, we should always cite where it came from as well as the methods of how that data was obtained. ...

There has been a growing effort to replace manual extraction of data from research papers with automated data extraction based on natural language processing, language models, and recently, large language models (LLMs). Although these methods enable effi
The extraction step occurs when you identify and copy or export the desired data from its source, such as by running a database query to retrieve the desired records. The transformation step is the process of cleaning the data so that they fit the analytical need for the data and the schem...
Data extraction Value-tick ratio calculation: This ratio is used to calculate the y-values from each bar-plot using the pixel projection method. Y-axis ticks are detected by left-bounding boxes to the y-axis. Since the text detection (numeric values) isn't perfect, once the pixel values ...
(iii) SGATE-HSG performs better than SGATE-HSG-N, which indicates that our trained visual features extraction model adopted from ResNet-50 by data augmentations and contrastive learning did learn more rich visual features than those from naïve ResNet-50 model pre-trained by ImageNet; (iv) ...
individuals based on experience and consistency across channels and data sets are some of the criteria that are commonly used. Finally, it should be noted that the process of data acquisition and cleansing is not static, but involves feedback from the feature extraction and feature comparison ...
