Dr. Molly Frame of Stony Brook University, New York, uses the ProAnalyst Cell Tracking toolkit to perform her microbiological research. This video shows tracked cells moving through veins and arteries. The Cell Tracking toolkit also computes flow direction, proximity to cellular walls, and more. This toolkit is ideal for researchers studying cell motion or cavitation in pipes.
Equine biomechanics researchers rely on ProAnalyst to obtain the measurements and analysis required to identify ways for horses to run faster and more efficiently. Researchers can also draw conclusions about an animal's health, age, and speed from its gait pattern. In this video, ProAnalyst's markerless feature tracking measures the stride of a racehorse. Dynamic measurements quantify the angles of the legs as the horse runs on the track.
Facial Landmarking Kinematics
This video outlines how ProAnalyst 3-D is being deployed to measure and archive common 3-D facial landmarks to build a highly accurate 3-D model of the face. This technique uses multiple high-speed videos captured using ProCapture and analyzed with 2-D feature tracking templates created within ProAnalyst. ProAnalyst 3-D Manager combines the individually analyzed 2-D datasets to form detailed and accurate 3-D location and motion data from the assembled stereoscopic facial video.
Common facial expressions and activities such as smiling, talking and chewing are recreated to form a pre-surgery baseline for the kinematics of the facial landmarks. This baseline can be compared to post-surgical kinematic results to develop a quantitative map of facial elasticity loss.
ProAnalyst has seen over a decade of widespread adoption within the medical research community and has become a trusted research tool for video measurement and verification by surgical leaders in both hospitals and universities worldwide.
ProAnalyst can be used to quantify and track facial landmarks in 3D when captured from 2 or more sterioscopically linked cameras. This can be used to extract very accurate position data and compare that data to previously captured facial data. In this instance 4 cameras capture multiple angles of the subject and create a 3D reconstruction with accurate 3D measurements of facial data that do not relay on relative ratios.
Functional morphology is the relationship between the structure and function of human or animal features. At the University of Chicago, Dr. Callum Ross leads a research program in evolutionary morphology focusing on comparative biomechanics of the head, with special emphasis on the feeding systems of primates, crocodilians, and other vertebrates.
Oftentimes, the motion of the animal that needs to be studied is not on the outside of the body. In those cases, X-ray images are used to visualize the bone motion under the skin. X-ray machines can refresh very quickly, so Xcitex ProCapture high-speed cameras are placed to image the X-ray phosphor tubes. This new technique, pioneered at Brown University in Rhode Island, Stony Brook University in New York, and the University of Chicago, enables researchers to analyze exact bone motion.
This image shows a primate eating and swallowing. Feeding function and behaviors are essential for animal survival, and help provide insight into human larynx issues. In this instance, the researchers used a combination of MiDAS DA and ProAnalyst motion analysis software to capture the vital signs and forces. ProAnalyst 1-D Line Tracking is used to quantify speed and position as the jaw opens and closes.

In the Functional Morphology and Primate Locomotion Laboratory at Stony Brook University, one of the world's leading institutions for the study of anthropological morphology, a research team led by Dr. Brigitte Demes studies the bipedal gait of chimpanzees. Since humans and chimps share a common ancestor, her research also informs conclusions about the evolution of human posture and gait.
The researchers at Stony Brook record 3-D kinematic video using the Xcitex ProCapture motion capture system with video and data options, ProAnalyst 3-D Professional Edition, and a custom-built 3-D calibration fixture in their laboratories. A chimpanzee walks along a specially constructed runway. Embedded within the runway are very sensitive force plates that record the pressure placed by the primate's feet as a function of body position and time. ProCapture captures the action from four different viewpoints and automatically synchronizes the video with the force plate data to create a multi-dimensional model of the walking motion. Electromyographic (EMG) data are captured wirelessly through a telemetry system and synchronized with video recordings of the subject's behavior.
Later, the videos and data are analyzed with ProAnalyst motion analysis software and the results melded to created a full 3-D reconstruction of the chimp's gait with quantifying motion analysis data and synchronized force plate data. This data has been presented for review at the annual Society of Integrated Biology conference for many years to great acclaim.
Have fun watching this video of the Robosapien toy. Xcitex engineers recorded a short dance routine using a pair of high-speed cameras. Bringing both videos into ProAnalyst, the engineers were able to easily create a 3-dimensional (X-Y-Z), precise reconstruction of the movement. 3-D analysis within ProAnalyst is easy; it provides greater understanding of motion than conventional 2-D, single view video.
As this toy robot performs a short dance routine, ProAnalyst's stick figure overlays delineate the movements of arms, legs, and torso. This analysis is an example of kinematics, the study of the motion of systems composed of joined parts, such as the body of this robot. Kinematic analysis is used to study range of movement and also to design machines with a required range of motion.
Human Jumping Kinesiology
This video shows a human subject jumping. ProAnalyst was used to track and connect several features to highlight the biomechanics of jumping. Video analyses like these are used by researchers who study kinesiology -- an interdisciplinary field focusing on the science of human movement, performance, and function. In recent years, the field of kinesiology has evolved toward less emphasis on sport and a greater focus on understanding human movement and the role of physical activity and exercise in health and disease. Applications of kinesiology in human health include physical education, physical and occupational therapy, and rehabilitation.
Kangaroo Rat Locomotion
University of Idaho researcher Dr. Craig McGowan used a ProCapture motion capture system to record the hopping movements of this desert kangaroo rat. Dr. McGowan then used ProAnalyst motion analysis software to track several points on the body. A feature line configured with dynamic 3-point angle measurements displays the range of motion in the animal's lower leg. This analysis of the animal's locomotion combined with data from force plates sheds new light on acceleration biomechanics in bipedal hoppers.
Patients affected by movement disorders are participating in neurobiological research conducted by Dr. Michelle Burack of the University of Rochester Medical Center. In this video we see the effects of tremors causing involuntary movements in the patient's head, arms, and hands. This video was recorded with the ProCapture video capture system. ProCapture's high-speed cameras and long-recording capability are ideal for easy motion capture in the lab or the field. Dr. Burack applies the knowledge gained from her research to refine treatment and provide enhanced benefits with fewer side effects for patients living with movement disorders such as Parkinson's disease.
This video showcases the research of Dr. Elizabeth Davis-Berg, Professor of Biology at Columbia College of Chicago. Here, ProAnalyst's Particle Tracking toolkit counts and categorizes food particles in the water flowing around some barnacles. This toolkit, designed for statistical analysis of particle flows, allows classification of particles by size, shape, eccentricity, or axial orientation. It is also useful for sprays, injectors, plumes, and impact studies. The Particle Tracking toolkit estimates the path or velocity of particles by establishing correspondences for all particles from frame to frame of the video. Particle trails can also be configured to show the entire estimated trail for each visible particle.
ProAnalyst is used extensively by the biomechanics and locomotion research community to study how animals have evolved and how animals/humans walk. This research has resulted in a greater understanding of sports performance, movement disorders and injury rehabilitation. In this example, a gecko scales a vertical wall under the watchful eye of ProAnalyst and a high-speed camera.
In this video, biomechanics researchers analyzed the spinal motion of a gecko walking on a photoelastic track. Data from the automatic feature tracking is graphed directly below the video. ProAnalyst simultaneously plots x-coordinate vs. time for four features.
Medical researchers have adapted MiDAS DA software as the standard for capturing videos of heart valve movement while simultaneously collecting data from flow sensors. Here, MiDAS Waveform Per Frame™ technology synchronizes video images of heart valve movement and flow pressure data with unparalleled accuracy.
Using ProAnalyst 1D Line tracking and Contour tracing, medical device manufacturers are able to study and perfect the flow patterns of artificial heart valves. Video can be synced with external DAQ EKG data.
