Fusion detection in time-lapse microscopy images : application to lipid droplets coalescence in plant seeds

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...

Automated 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 ...

Plant Classification in Images of Natural Scenes Using Segmentations Fusion

This paper presents a novel approach to automatic classifying and identifying of tree leaves using image segmentation fusion. With the development of mobile devices and remote access, automatic plant identification in images taken in natural scenes has received much attention. Image segmentation plays a key role in most plant identification methods, especially in complex background images. Wher...

Apoptosis Detection for Adherent Cell Populations in Time-Lapse Phase-Contrast Microscopy Images

The detection of apoptosis, or programmed cell death, is important to understand the underlying mechanism of cell development. At present, apoptosis detection resorts to fluorescence or colorimetric assays, which may affect cell behavior and thus not allow long-term monitoring of intact cells. In this work, we present an image analysis method to detect apoptosis in time-lapse phase-contrast mic...
