Automating your Daily Image Analysis Tasks with Amira Software


Lecturer

Jan Giesebrecht
Thermo Fisher Scientific
Germany
 
Brief Bio
After a decade of image processing work and lecturing medical students at the largest university clinic in Europe – the Charité Berlin – Dr. Giesebrecht joined Thermo Fisher Scientific addressing all kinds of image analysis problems in the Life Sciences and Materials Science.
Abstract

Powerful image processing tools are essential to the modern researcher's workflow. Thermo Scientific Amira Software now comes with a new mechanism to store and execute proven image data processing workflows for massive image data sets. During this tutorial, you will learn how Amira Software can automate and speed up your image analysis when dealing with many data sets from the same origin and with the same analytical question. The workflow creation process will be explained and demonstrated using a life science dataset, including steps such as image filtering, segmentation, or the extraction of user-defined statistics from the data. Recipes can be easily shared with your peers, and form an easy-to-use foundation for your routine image analysis tasks.

Simulations of Cell Flow in Microchannels with Object-in-fluid Module in open-source ESPResSo Software Package


Lecturer

Ivan Cimrak
University of Zilina, Cell-in-fluid Biomedical modelling and computations group
Slovak Republic
 
Brief Bio
After his PhD and a post-doc studies in numerical mathematics at Ghent University, Belgium, Dr. Cimrak focused his research interests on cell flow modelling. He founded a Cell-in-fluid Biomedical Modelling and Computations group at University of Zilina, with currently more than 10 members. His research topics are since then all aspects of biomechanical cell modelling, biomedical image and video data processing, and machine learning algorithms in biomedical image processing.
Abstract

Laboratory experiments involving flow of cells inside microchannels have been used in many research areas involving cell separation, rare cell isolation, tumour cell capture, various types of cell manipulation, etc. Computational modelling and even more specifically, the computer implementation of these models, allow to simulate processes inside such microfluidic devices and to tackle frontiers of the state-of-the-art microfluidic platforms. We have developed a module Object-in-fluid within the open-source scientific package ESPResSo that enables simulation of individual cells with their specific elastic properties. Object-in-fluid is based on the coupled lattice Boltzmann - immersed boundary method, fully resolving the mechanics of the cells and their interactions with blood plasma. These models help predict the transport of cells in microfluidic flows. In this tutorial we learn basics of cell mechanics and the development of underlying models. We will create simple scripts and we will have hands-on session with the module Object-in-fluid.

From Offline towards Real-Time: a Wearable HAR System Using Biosensors Integrated into a Knee Bandage


Lecturer

Hui Liu
University of Bremen
Germany
 
Brief Bio
Hui Liu joined Cognitive Systems Lab at University of Bremen as Researcher for wearable devices and biosignal processing on Mai 16, 2016.
Abstract

During this tutorial, we will introduce a framework for the acquisition, processing and application of biosignals recorded from biosensors integrated into a knee bandage. Such a framework involves the appropriate equipment in devices and sensors, the long-term recording and archiving of corresponding multi-sensory biosignal data, the semi-automatic annotation and segmentation of these data, and the HAR (Human Activity Recognition). You will understand not only how to build an offline HAR system, but also how to realize a real-time HAR system based on the offline foundation. Plenty of topics relating to the real-time HAR will be covered in this tutorial, including the experimental tuning of system parameters which balances recognition accuracy with real-time performance, the intuitive visualization of biosignals as well as n-best recognition results in the graphical user interfaces, and the on-the-air extensions for rapid prototyping of applications.
