The on-site event at MICCAI 2016 will take place Monday, October 17th, 14:00-18:00, in Omikron II, with the following program:
- Introduction, Jan Funke
- Keynote I, Juan Nunez-Iglesias (VLSCI, University of Melbourne, Australia)
- Presentation by group IAL, category neuron segmentation
- Keynote II, Anna Kreshuk (HCI Heidelberg)
- Coffee break
- Presentation by group DIVE, category neuron segmentation and synaptic cleft detection
- Presentation by group SDG, category synaptic cleft detection
- Keynote III, Srinivas Turaga (Janelia Research Campus)
The goal of this challenge is to evaluate algorithms for automatic reconstruction of neurons and neuronal connectivity from serial section electron microscopy data. The comparison is performed not only by evaluating the quality of neuron segmentations, but also by assessing the accuracy of detecting synapses and identifying synaptic partners. The challenge is carried out on three large and diverse datasets from adult Drosophila melanogaster brain tissue, comprising neuron segmentation ground truth and annotations for synaptic connections. A successful solution would demonstrate its efficiency and generalizability, and carry great potential to reduce the time spent on manual reconstruction of neural circuits in electron microscopy volumes.
Datasets and Challenge Categories
We provide three datasets, each consisting of two (5 μm)3 volumes (training and testing, each 1250 px × 1250 px × 125 px) of serial section EM of the adult fly brain. Each volume has neuron and synapse labelings and annotations for pre- and post-synaptic partners.
Submissions can be made in the following categories:
- Assessment of neuron labelings in terms of pixel-based measures (Rand index and variation of information) and topological correctness (Tolerant Edit Distance). Winners will be determined using a weighted average of the scores.
- Synapse Detection
- Detection of synapses. Winners are determined using the F-measure of false positive and false negative detections.
- Identification of synaptic partners. Winners are determined using the F-measure of false positive and false negative detections of pre- and post-synaptic pairs.
Details about the evaluation procedures will be released soon.
