Automated analysis of time lapse microscopy images
Cells are the building blocks of life, and time lapse microscopy is a powerful way to study cells. Automated video acquisition and analysis of cells opens unprecedented opportunities, ranging from building novel mathematical models supported by rich data to automated drug screening. Unfortunately, accurate and completely automated analysis of cell images is a difficult task. Therefore human int...
متن کاملSuper resolution of time-lapse seismic images
We present results of an on-going project to assess the applicability in reflection seismology of emerging super resolution techniques pioneered in digital photography. Our approach involves: (1) construction of a forward model connecting low resolution seismic images to high resolution ones, and (2) solution of a Tikhonov-regularized ill conditioned optimization problem to construct a high res...
متن کاملImage-domain time-lapse inversion with extended images
Time-lapse seismic data is used to monitor subsurface changes occurring between consecutive surveys. One way to look at the differences is to create images from each survey and simply subtract them to obtain a difference. It is possible to model image differences directly from the slowness change between two surveys: this leads to a forward modeling operator that essentially performs differenti...
متن کاملApparent horizontal displacements in time-lapse seismic images
In addition to vertical time shifts commonly observed in time-lapse seismic images, horizontal displacements are apparent as well. These apparent horizontal displacements may be small relatively to seismic wavelengths, perhaps only 5 m at depths of 5 km, but they consistently suggest an outward lateral expansion of images away from a compacting reservoir. It is well known that apparent vertical...
متن کاملAutomated Cell Volume Estimation in Time-Lapse Microscopy Images
Understanding the genes involved in cell volume regulation is an important area in biological research. Modern screens involving RNA interference often involve analyzing many thousands of cells, and manual techniques are too slow. We describe a fully automated method for estimating the volume of spherical mitotic cells, within given bounds, based on a learned membrane classifier and a circular ...
