We describe a new method for counting fishes, and estimating relative abundance (MaxN) and fish density using rotating stereo-video camera systems. We also demonstrate how to use distance from camera (Z distance) to estimate species-specific detectability.

This protocol uses multi-view stereo to generate three-dimensional (3D) models out of uncalibrated sequences of photographs, making it affordable and adjustable to a surgical setting. Strain maps between the 3D models are quantified with spline-based isogeometric kinematics, which facilitate representation of smooth surfaces over coarse meshes sharing the same parameterization.

Stereo-electroencephalography (SEEG) aids in localization of epileptogenic zones, however, remains relatively underutilized in the United States. The goal of this abstract is to provide a brief introduction to the technique of SEEG and further a detailed technique of using robotic assistance in the placement of SEEG electrodes.
FAQs
The process first locates matching features in the left and right images, then measures their disparity, meaning the positional difference between corresponding features. Geometric triangulation uses that disparity to estimate depth. This sequence connects image matching with three-dimensional structure, while the time limit requires both stages to produce spatial information within the predefined processing window.
A stricter processing deadline limits how much computation can be devoted to correspondence and depth estimation. Time Constrained Stereo therefore treats reconstruction quality and processing speed as linked objectives rather than separate concerns. Its usefulness comes from producing sufficiently informative three-dimensional perception while respecting the timing requirements of systems that must interpret image data promptly.
Depth quality depends on how reliably the system identifies corresponding features and how effectively it converts their disparity through geometric triangulation. Errors in matching can affect the resulting spatial estimate, while the available processing time constrains the computations used to obtain it. These factors make correspondence performance, geometric processing, and the time constraint central to reconstruction outcomes.
A typical workflow begins with paired left and right images, followed by stereo correspondence to identify shared features. The system then determines the disparity between those features and applies geometric triangulation to estimate depth. Finally, the reconstruction is produced within the specified processing limit, creating three-dimensional information that can support time-sensitive interpretation.
In medicine, the approach may be applied to endoscopic image data or other paired medical images when spatial information must be interpreted quickly. By combining depth estimation with a predefined time constraint, it can support real-time three-dimensional perception during image-guided procedures. The resulting spatial information may also assist clinical decision-making when delayed processing would reduce practical value.
The method can provide an estimate of three-dimensional structure from paired medical views, rather than leaving interpretation limited to separate two-dimensional images. In image-guided procedures, that spatial information may help systems present more timely geometric context. Its relevance is greatest when clinicians or procedure-support systems need useful depth information without waiting for unconstrained computational processing.
