AMIS
Microscope Smart Sensors
The AMIS project aims to develop a next-generation adaptive microscope control system with automated image analysis tools for detection and tracking of living cells in high temporal-spatial resolution. Such high-throughput screening systems will replace the currently prevalent practices of visual inspection and manual analysis by delivering results with unprecedented efficiency, completeness and consistency, and is thus ready for thorough statistical evaluation of large-scale datasets.
Our research focuses on the following issues:
- Development of effective, robust algorithms of cell detection and tracking for fluorescent microscopes
- Exploiting the parallelism of hardware computing in image preprocessing for high throughput applications
- Investigation of effective data reduction and management strategies to cope with the immense volume of image data
- Exploring the optimized constellations and integration strategies of heterogeneous microprocessors in embedded vision systems with high-throughput and high-content analysis requirements
- Integration and interfacing with the image acquisition and control logic units on a next-generation microscope platform with self-adaptation capabilities
- Streamlining the methodology of hardware/software co-design for embedded computer vision systems
A powerful, versatile, yet efficient image analysis system is decisive to automating the high-throughput imaging experiments of living cells. The following processing pipeline is proposed to intelligently handle the immense volume of data with on-the-fly extraction of relevant information for cell property analysis and adaptive microscope control to retain the optimal experimental conditions.
To meet the stringent real-time requirement for adaptive microscope control, the cell detection and tracking algorithms are implemented in a heterogeneous multiprocessor embedded system with FPGAs and DSPs and integrated into a next-generation microscope platform.
