In this tutorial we will take a look at the powerfulgeopandaslibrary and use it to plot a map of the United States. You can run all of the python code examples in the tutorial by cloning the companion github re
We also developed a user-friendly pipeline for human-in-the-loop annotation and model retraining. An annotator using our graphical user interface (GUI) was able to generate state-of-the-art models in 1–2 hours per category. Results Human annotators use diverse segmentation styles The ...
Let’s start with the “hello world” of t-SNE: a data set of two widely separated clusters. To make things as simple as possible, we’ll consider clusters in a 2D plane, as shown in the lefthand diagram. (For clarity, the two clusters are color coded.) The diagrams at right show...
Matplotlib in python offers some useful tools for plotting with gradient colors. Below is a script that plot a sine wave with gradient color based on its y-value. It shows the use of matplotlib.cm.get_cmap to obtain a color map and the use of matplotlib.colors.Normalize to convert a val...
Pretrained neural network models for biological segmentation can provide good out-of-the-box results for many image types. However, such models do not allow users to adapt the segmentation style to their specific needs and can perform suboptimally for te
The dataset is small, containing only 877 images in total. While you may want to train with a larger dataset (like the LISA Dataset) to fully realize YOLO’s capabilities, we use a small dataset in this tutorial to facilitate quick prototyping. Typical training takes less than half an hour...
A picture may be worth a thousand words,but a chart can tell the story of millions of data points. Charts, maps, and even well-formatted tables can turn numbers into stories. Persuasive presenters use them to back up bold assertions. Curious investigators uncover patterns or anomalies in the...
If you wish to change the Colormap of the heatmap, you can do so by referring to the Ultralytics Docs: Heatmap Colormaps. For a more effective image display, you can adjust the heatmap_alpha value, as demonstrated in the code snippet: # Heatmap initialization heatmap_obj = heatmap....

The AI gave me four charts (like the example below), one for each ethnicity it was tracking. Note the phrase "Matplotlib Chart" at the top of the chart. As you can see, I tried very hard to get ChatGPT to remove it and other wacky titles it chose to use from the charts, but...
