We present a fully automated, adaptive, and robust feature-based cell tracking algorithm for the accurate detection and tracking of cells using time-lapse images. Our algorithm tackles measurement limitations twofold. First, we use Hessian filtering and adaptive thresholding to detect the cells in images, overcoming spatial...

With advancements in biotechnology, the production of highly concentrated antibody formulations for subcutaneous injections is becoming common in the biopharmaceutical industry. Measurement of transport and more importantly diffusion of proteins in tissues is essential in drug development. There is evidence suggesting that the assumption of the...

Particle Image Velocimetry (PIV) is a widely used non-invasive approach to finding a fluid flow velocity using tracer particles. Performing PIV measurement where the Signal-to-Noise Ratio (SNR) in the correlation plane is low can be unreliable and challenging. To address this issue, ensemble PIV has...

4D flow magnetic resonance imaging (MRI) allows for in vivo acquisition of time-resolved three-dimensional (3D) blood flow, thus enabling quantitative analysis of volumetric, time-varying hemodynamic quantities such as flow rates, wall shear stress (WSS), pressure difference, etc. 4D flow MRI is based on the phase...

The value of the flowing soap film as an experimental platform depends on its ability to approximate the two-dimensional Navier-Stokes equation. A variety of experimental techniques have been applied to characterize the soap film patterns, with the measured quantities being the thickness and the velocity...
