We describe a novel methodology for creating naturalistic 3-D objects and object categories with precisely defined feature variations. We use simulations of the biological processes of morphogenesis and phylogenesis to create novel, naturalistic virtual 3-D objects and object categories that can then be rendered as visual images or haptic objects.

Object Substitution Masking

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual masking is a term used by perceptual scientists to refer to a wide range of phenomena in which in an image is presented but not perceived by an observer because of the presentation of a second image. There are several different kinds of masking, many of them relatively intuitive and unsurprising. But one surprising and important type of masking is called Object Substitution Masking. It has been a focus of research in vision...
FAQs
The model first uses visual features to determine whether the target belongs to the intended object category, then estimates where that target appears in the frame. A bounding box records the estimated location, while the confidence score communicates how strongly the model supports that result. Together, these outputs provide a structured basis for selecting frames for later behavioral measurements.
Consistent localization gives researchers a repeatable reference for measuring where a focal animal, person, or device is positioned across successive frames. This matters because behavioral conclusions can depend on changes in position, movement, or interactions. By applying the same detection approach throughout an observation, the analysis becomes more reproducible than relying entirely on variable manual annotation.
Manual annotation requires a person to identify the focal target repeatedly, whereas an automated model can process image or video frames using the same detection procedure. This can reduce annotation demands and make observation more scalable. The resulting detections also provide standardized locations and confidence scores that help organize subsequent measurements across many frames.
Successive frames allow the detected location to serve as a basis for examining change over time. Researchers can use these frame-by-frame observations to assess position and movement, and to relate those patterns to interactions visible in the recording. This temporal structure connects individual detections with broader behavioral sequences rather than treating each frame as an isolated observation.
A typical workflow begins with an image or video frame containing the focal animal, person, or device. The model analyzes visual features, classifies the target, estimates its location, and records a bounding box with a confidence score. Researchers can then use the resulting locations across frames to measure position, movement, or interactions and compare them with experimental conditions.
Researchers would apply it when a study requires repeated observation of one focal animal, person, or device in images or video. The approach is especially relevant when manual tracking would be time-consuming or difficult to scale. It supports systematic measurement across successive frames and helps connect visible behavior with environmental conditions or experimental treatments.
The detected location becomes an input for examining behavioral variables that change across frames. From these observations, researchers can characterize position and movement and assess interactions involving the focal target. When the recordings are paired with environmental conditions or experimental treatments, the measurements can also support analysis of how those factors relate to visible actions.
A consistent detection procedure reduces dependence on ad hoc decisions made during repeated manual annotation. Each analyzed frame can receive a comparable target location and confidence score, creating a standardized record for later measurement. This supports more reproducible behavioral analysis and makes it easier to scale observations across recordings while preserving links to treatments or environmental conditions.
