In video-records, objects moving in intracellular regions are often hardly detectable and identifiable. To squeeze the information on the intracellular flows, we propose an automatic method of reconstruction of intracellular flow velocity fields based only on a recorded video of an unstained cell. The basis of the method is detection of speeded-up robust features (SURF) and assembling them into trajectories. Two components of motion—direct and Brownian—are separated by an original method based…

Content-Based Image Retrieval and Feature Extraction: A Comprehensive Review
TLDR
A comprehensive review of the recent development in the area of CBIR and image representation is presented and the main aspects of various image retrieval and image representations models from low-level feature extraction to recent semantic deep-learning approaches are analyzed.
Quasi-spectral characterization of intracellular regions in bright-field light microscopy images
TLDR
A method of a physically correct extraction of features for each pixel when these features resemble a transparency spectrum is introduced and it is believed that this method is the right approach to an intracellular (semi)quantitative and qualitative chemical analysis.
Quantitative Viscosity Mapping Using Fluorescence Lifetime Measurements
TLDR
The appropriateness of standard methods used in tribology for high-pressure rheometry (combining friction and film thickness measurements) has been verified when the flow of EHD lubricant is homogeneous and linear.
Robust regression using iteratively reweighted least-squares
The rapid development of the theory of robust estimation (Huber, 1973) has created a need for computational procedures to produce robust estimates. We will review a number of different computational
Lagrangian measurement of vorticity dynamics in turbulent flow
The full set of velocity derivatives, $\partial u_{i}/\partial x_{j}$, is measured experimentally in a Lagrangian way in quasi-homogeneous isotropic turbulence. This is achieved by applying the
BioFlow: a non-invasive, image-based method to measure speed, pressure and forces inside living cells
TLDR
The power of BioFlow is illustrated in the context of amoeboid cell migration, by modelling the intracellular actin bulk flow of the parasite Entamoeba histolytica using fluid dynamics, and report unique experimental measures that complement and extend both theoretical estimations and invasive experimental measures.
Development of measuring diffusion coefficients by digital holographic interferometry in transparent liquid mixtures.
TLDR
The method of using the distance of the peaks in concentration difference profile to determine diffusion coefficient by Mach-Zehnder interferometric experimental setup is used, which can be more convenient and accurate to determine the distance between the two peaks.
