Virtual 4D Model: Visualising The Growing Caryopsis (Barley-Hordeum vulgare L.) in Three Directions

The shape of the maternal pericarp affects cereal grain mass and yield. Pericarp growth was analysed by magnetic resonance imaging (MRI), revealing topological maps of mobile water in developing pericarp of barley (Hordeum vulgare) and displaying tissue regions actively elongating in specific temporal–spatial patterns.

Image warping is a process of transforming one (source) image to a second (target) image by redefinition of the spatial relationships between the pixels. It can be based on matching of certain image features such as important points (landmark-based) or on matching of local grey value (or colour) distributions (intensity-based). Intensity-based warping was used to combine normalized 3-D in vivo MRI images of successive developmental stages into a virtual 4-D model visualising the growing caryopsis (longitudinal direction; cross direction; saggital direction)

Embark on a virtual journey through the dynamic development of a caryopsis! This video presents a stunning 4-dimensional (4D) model that visualizes the intricate growth processes.
