Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...

This type of wing has a small aspect ratio and high sweep angle, which reduces drag at high subsonic, transonic and supersonic flight regimes. The aspect ratio is defined as the wing span divided...

We have developed a video-rate tracking microscope system that can record and quantify C. elegans behavior at high resolution and high speeds. We have also developed computational methods to reduce the dimensionality of the worm images to a fundamental set of measurements that completely describe the shape of the worm.

Eye tracking has long been used to study gaze patterns in typically-developing individuals, but recent technological advancements have made its use with clinical populations, including autism, more feasible. While eye-tracking young children with autism can offer insight into early symptom manifestations, it involves methodological challenges. Suggestions for best practices are provided.
FAQs
The calculation begins with detected edge positions and links those positions either across neighboring pixels or through successive frames. The resulting boundary segments or trajectory segments are then summed to obtain the measured length. This approach makes the value dependent on which biological feature is followed and whether the analysis describes a spatial boundary or movement over time.
Reliable results depend on consistently identifying the relevant edge and maintaining its positional linkage across the available pixels or frames. Microscopy and sensor images can describe different biological structures or interfaces, so the selected edge must match the feature being studied. Consistent tracking is important when measurements are compared across biological dynamics or used in image-based modeling.
A change in the tracked length can indicate altered motility, growth, remodeling, or mechanical response, depending on the feature and experiment. For example, following a moving cellular or tissue boundary over successive frames can expose changes in its behavior, whereas tracking a structural boundary can reflect changes in geometry. Interpretation therefore depends on the biological context.
Boundary analysis emphasizes the summed segments that describe the shape or extent of an interface, while motion analysis links positions across successive frames to describe a trajectory. Both use edge information, but they answer different questions. The first supports measurements of geometry or deformation; the second supports analysis of movement, including changes associated with cell migration or wound closure.
A typical workflow starts with microscopy or sensor images, identifies the edge of the selected biological feature, links its position across pixels or successive frames, and sums the resulting segments. The final measurement can then be compared across samples or time points. This workflow converts image-based observations into a quantitative basis for evaluating biological dynamics.
Edge tracking can be applied to cell migration, tissue deformation, vessel geometry, wound closure, and flow-driven interfaces in microfluidic systems. These applications use the tracked boundary or feature to quantify spatial form or temporal behavior. The resulting measurements support image-based modeling and comparisons of how biological structures move, grow, remodel, or respond mechanically.
