Query: Computer vision for liquid samples in hospitals and medical labs using
  hierarchical image segmentation and relations prediction   This work explores the use of computer vision for image segmentation and
classification of medical fluid samples in transparent containers (for example,
tubes, syringes, infusion bags). Handling fluids such as infusion fluids,
blood, and urine samples is a significant part of the work carried out in
medical labs and hospitals. The ability to accurately identify and segment the
liquids and the vessels that contain them from images can help in automating
such processes. Modern computer vision typically involves training deep neural
nets on large datasets of annotated images. This work presents a new dataset
containing 1,300 annotated images of medical samples involving vessels
containing liquids and solid material. The images are annotated with the type
of liquid (e.g., blood, urine), the phase of the material (e.g., liquid, solid,
foam, suspension), the type of vessel (e.g., syringe, tube, cup, infusion
bottle/bag), and the properties of the vessel (transparent, opaque). In
addition, vessel parts such as corks, labels, spikes, and valves are annotated.
Relations and hierarchies between vessels and materials are also annotated,
such as which vessel contains which material or which vessels are linked or
contain each other. Three neural networks are trained on the dataset: One
network learns to detect vessels, a second net detects the materials and parts
inside each vessel, and a third net identifies relationships and connectivity
between vessels.
