Hi, you should give scikit-image (https://scikit-image.org/) a try! It has many features for objects detection and labelling, see for instance the following examples Label Image regions : https://scikit-image.org/docs/dev/auto_examples/segmentation/plot_label.html#sphx-glr-auto-examples-segmentation-plot-label-py Blob detection : https://scikit-image.org/docs/dev/auto_examples/features_detection/plot_blob.html#sphx-glr-auto-examples-features-detection-plot-blob-py Measure region properties : https://scikit-image.org/docs/dev/auto_examples/segmentation/plot_regionprops.html#sphx-glr-auto-examples-segmentation-plot-regionprops-py Fabrice
