CoDA: Interactive Segmentation and Morphological Analysis of Dendroid Structures Exemplified on Stony Cold-Water
IEEE Transactions on Visualization and Computer Graphics
|February 3, 2026
Summary
A new toolkit, CoDA (Coral Dendroid structure Analyzer), enables systematic analysis of complex stony coral skeletons. This tool reconstructs coral colony structures for detailed ontogenetic morphological studies, aiding reef-building research.
Area of Science:
- Marine Biology
- Computational Biology
- Geology
Background:
- Dendroid stony corals form complex, tree-like colonies vital for reef ecosystems.
- Previous studies lacked systematic methods for analyzing coral colony ontogenetic morphology due to structural complexity.
Purpose of the Study:
- To introduce CoDA (Coral Dendroid structure Analyzer), a visual analytics toolkit for reconstructing dendroid coral skeleton trees.
- To enable systematic ontogenetic morphological analyses of complex coral colonies.
Main Methods:
- Instance segmentation of coral calices (corallites).
- Automated estimation and interactive correction of skeleton trees.
- Utilizing CoDA.Graph for link-and-brush visualization of morphological features and graph layouts.
Main Results:
- CoDA successfully reconstructs skeleton trees for complex dendroid stony corals.
- The toolkit facilitates proofreading and correction of segmentation and skeleton tree data.
- Demonstrated utility on multiple cold-water coral species with diverse morphotypes.
Conclusions:
- CoDA provides the first systematic approach to analyzing dendroid coral colony ontogenetic morphology.
- This tool enhances the study of coral reef builders and their ecological significance.

14.8K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

02:39Predator-Prey Interactions
21.7K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

01:23States of Water
57.0K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

01:27Cold Weather Concreting
384
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.

02:34Water and Mineral Acquisition
35.8K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

87.9K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
