Drosophila embryo

The dataset contains frontal slices of light-sheet microscopy images of Drosophila embryos. For further details of the imaging procedure refer to the paper in references.

Structure:

• train (307 files):
  • graph_data - HDF files with graphs node features;
  • pix_data - HDF files with raw images, superpixels, and edge maps;
• val (10 files):
  • graph_data - HDF files with graphs node features;
  • pix_data - HDF files with raw images, superpixels, edge maps and ground truth.

Each image file contains:

• node_labeling: superpixel map (sp);
• ps_edge: edge map obtained from the PlantSeg network;
• raw: raw image (single channel);
• sp_edge: edge map obtained from the superpixel map;
• gt: ground-truth labels (provided only for validation).

Each graph file consists of:

• offsets: set of offsets used for affinity maps;
• affinities: affinity map (for each offset);
• edges: all neighboring edges, (sp_i, sp_j);
• edge_feat: computed features for each edge;
• gt_edge_weights: the same partitioning as edges but with labels (label each edge pertains to), only for validation set.
