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 ...

Extracting data from a surface, through time, using PyTecplotIn this example we want to extract Pressure values through time from the wall of a simulation at specific XYZ locations. After the extractions, we want to plot the results with Time on the X-Axis and Pressure on the Y-Axis for...
The onlineWebPlotDigitizertool can be very useful in data science and in petrophysics to extract data from graphics when the raw data source is unavailable. However, when extracting this data, be aware of the accuracy of the picked points. They are only as good as the ...
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 ...
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
Where quantitative information was only available in charts, we used WebPlotDigitizer version 4.2 for data extraction37. While most data sources reported only summary measures, namely mean mortality figures for multiple flocks, some reported mortality data for each individual flock. In such cases, we...
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 steps.
