In consequence, we significantly decrease the amount of annotations needed for a given training set. We apply the proposed loss to train DNNs for segmentation of vascular and neural networks in microscopy images and demonstrate only a marginal accuracy loss associated to the significant reduction of the annotation effort. The lower labor cost of deploying DNNs, brought in by our method, can contribute to a wide adoption of these techniques for analysis of 3D images of linear structures.Computer Science, Theory & MethodsComputer Science 6531_image segmentationdeep learningdetection of linear structures in microscopy imagesneuron tracing in microscopy imagesextraction of blood vessels in microscopy imagestext::conference output::conference proceedings::conference paper
