A semantic and instance segmentation toolbox for EM connectomics.
The field of connectomics aims to reconstruct the wiring diagram of the brain by mapping the neural connections at the level of individual synapses. Recent advances in electronic microscopy (EM) have enabled the collection of a large number of image stacks at nanometer resolution, but the annotation requires expertise and is super time-consuming. Here we provide a deep learning framework powered by PyTorch for automatic and semi-automatic image segmentation in connectomics.

MitoEM Dataset: Large-scale 3D Mitochondria Instance Segmentation
Electron microscopy (EM) allows identifying intracellular organelles such as mitochondria, providing insights for clinical and scientific studies. We introduce the MitoEM dataset, a 3D mitochondria instance segmentation dataset with two (30 µm)^3 volumes from human and rat cortices, respectively, 3, 600× larger than previous benchmarks. With around 40K instances, we find a great diversity of mitochondria in shape and density. On MitoEM, we find existing instance segmentation methods often fail to correctly segment mitochondria with complex shapes or close contacts with other instances.

Electron microscopy (EM) enables the reconstruction of neural circuits at the level of individual synapses, which has been transformative for scientific discoveries. we introduce the AxonEM dataset, which consists of two 30×30×30 µm^3 EM image volumes from the human and mouse cortex, respectively. We thoroughly proofread over 18,000 axon instances to provide dense 3D axon instance segmentation, enabling largescale evaluation of axon reconstruction methods. In addition, we densely annotate nine ground truth subvolumes for training, per each data volume.

NucMM Dataset: Neuronal Nuclei Segmentation at Sub-Cubic Millimeter Scale
Segmenting 3D cell nuclei from microscopy image volumes is critical for biological and clinical analysis, enabling the study of cellular expression patterns and cell lineages. We pushed the task forward to the sub-cubic millimeter scale and curated the NucMM dataset with two fully annotated volumes: one 0.1 mm^3 electron microscopy (EM) volume containing nearly the entire zebrafish brain with around 170,000 nuclei; and one 0.25 mm^3 micro-CT (uCT) volume containing part of a mouse visual cortex with about 7,000 nuclei.

Pattern-Driven Navigation in 2D Multiscale Visualizations
Scalable Insets is a new technique for interactively exploring and navigating large numbers of annotated patterns in multiscale visual spaces such as gigapixel images, matrices, or maps.

Visualizing Intersecting Sets
Understanding relationships between sets is an important analysis task. The major challenge in this context is the combinatorial explosion of the number of set intersections if the number of sets exceeds a trivial threshold. To address this, we introduce UpSet, a novel visualization technique for the quantitative analysis of sets, their intersections, and aggregates of intersections.

HiPiler is an interactive visualization interface for the exploration and visualization of regions-of-interest (ROI) in large genome interaction matrices. ROIs can be defined, e.g., by sets of adjacent rows and columns, or by specific visual patterns in the matrix. ROIs are first-class objects in HiPiler, which represents them as thumbnail-like “snippets”. Snippets can be laid out automatically based on their data and meta attributes. They are linked back to the matrix and can be explored interactively.

Visually Interactive Neural Probabilistic Models of Language
This four-year project will employ a collaborative design process between researchers in visualization and machine learning. We aim to create neural architectures designed from the ground-up for visual interactivity allowing examination and correction. We will do this by designing neural probabilistic models that expose explicit “hooks” in the form of discrete latent variables determining model choices. We will apply these models to core tasks in natural language processing (NLP) including machine translation, summarization, and data-to-text generation, and design hooks that target important domain sub-decisions such as the showing the current topic cluster during text generation or the selected document sub-section during summarization.
