Distance-based ROI for object exploration quantification #501
Description
Is your feature request related to a problem? Please describe.
In animal behavior experiments, it is often necessary to define exploration based on the distance between the animal and an object. For example, exploration is usually considered valid only when the animal’s nose is at 1 cm or less from the object. Currently, it is difficult to accurately quantify this distance, which can lead to subjective or inconsistent scoring.
Describe the solution you'd like
I would like the software to include a tool that allows measuring the distance between the animal (e.g., nose position) and an object. After drawing a Region of Interest (ROI) over the object, the user could specify a fixed distance (for example, a 1 cm radius or diameter), and the software would automatically generate an expanded area representing that distance. This would allow exploration to be defined objectively based on proximity.
Describe alternatives you've considered
In other behavioral quantification programs, once the ROI is drawn over the object, the user can define a diameter of a specific size (e.g., 1 cm). The software then automatically adjusts or expands the ROI to match that distance, instead of requiring manual estimation.
Additional context
This feature would be especially useful in animal experimentation, where standardized and reproducible criteria for exploration are critical. Having an automatic distance-based ROI would improve accuracy, reduce user bias, and make results more comparable across experiments and users.
