-This `seg_carboseg(...)` function employs Python to implement a convolutional neural network (CNN) for segmentation as described by [Sipkens et al.][ptech.cnn] Details and code for the training of the network are available in a parallel repository at https://github.com/maxfrei750/CarbonBlackSegmentation, with primary contributions by Max Frei ([@maxfrei750](https://github.com/maxfrei750)). The implementation here makes use of the ONNX file output (to be downloaded [here](https://uni-duisburg-essen.sciebo.de/s/J7bS47nZadg4bBH/download)) from that procedure and employs the Python ONNX runtime for execution. Use of this function requires the necessary Python environment as a pre-requisite.
