SK3522 Quantitative Data Analysis and Processing for Microscopy7.5 credits

Kvantitativ databehandling och analys för mikroskopi

Advanced microscopy methods, such as confocal and super-resolution microscopy, generate large amounts of data. These data can often be represented as images and analyzed by different methods.
This course has an emphasis on methods for developing application-specific solutions to extract quantitative data from image information with Matlab, lmageJ and similar tools.

Third cycle

By agreement.

Intended learning outcomes

After completing the course, the student should be able to (with emphasis on image data from light microscopy)

• Explain and use the mathematical basis of intensity transformations and spatial filtering in up to four dimensions.
• Implement solutions based on this knowledge in Matlab, ImageJ, Imaris or similar computational toolkits, as well as use the built-in methods.
• Explain and use the mathematical basis of frequency domain filtering (Fourier methods) in up to four dimensions as well as deconvolution.
• Implement solutions based on this knowledge in the toolkit, as well as use the built-in functions
• Take into account the effects of color space choice, perform mathematically valid color space transformations and color-based transformations and segmentations
• Explain and use some basic mathematical algorithms for image compression
• Explain and use basic and coumpound morphological operations and implement solutions based on built-in methods.
• Explain and use the mathematical basis and methods of image segmentation.
• Implement solutions based on this knowledge in the toolkit, as well as use the built-in functions
• Know the advantages and challenges of working with different types of super­ resolution images (STORM, PALM, SIM, STED) and the mathematical foundations of the image (re)construction algorithms
• Extract relevant data from processed images and perform mathematical analysis thereof, including nonlinear regression, simple optimization problems and fitting to partial differential equations
• Build, motivate and document a GUI in Matlab, ImageJ or similar toolkit to handle a specific multi-step image processing and analysis task (project work)

This course focuses on the mathematical basis and implementation of microscopy image data processing, data extraction, and data analysis. The course covers intensity and color-based transformations and segmentations, Fourier methods for both filtering and analysis and morphological operations. The student will be expected to be able to both analytically solve problems and to independently choose methods and implement them to solve a "real" task.

Disposition

The course is based on 12 seminars where the theoretical aspects are addressed in parallel with the literature. The practical part of the course consists of two exercises and a larger project. The project should be related to the student's own research and process microscopy measurement data.

Eligibility

Admitted to PhD studies in Physics, Biological physics or related fields of study.
