Senior Trainer, Training Academy
As a biologist with a focus on neuronal development of insects and the structure of sialic acid binding neuronal proteins in mammals, Heiko Gaethje gained first experience with widefield and confocal fluorescence microscopy and image processing of 3D data.
Heiko joined Olympus in 2004 as a web content manager in the Marketing and Communication team. Since 2008, he has worked as a microscopy trainer at the Olympus Academy and is responsible for the conception and introduction of digital learning tools. In addition, he supports and conducts microscopy training courses at the EMBL Heidelberg and the Zurich Winter School on Advanced Microscopy where he regularly answers questions related to image processing and image analysis.

Deconvolution of 3D Image Stacks

Images taken with a light microscope are never true representations of the specimen. Error sources, which have to be controlled, are sample preparation and staining protocols as well as optical aberrations and limitations of microscope and digital camera.
Digital Image Processing: Point and Local Operation Filters (Encore Edition)
Thursday, 29 July, 2021
Experts
Want to get a better understanding of digital image processing techniques? Then watch our Ask the Experts webinar rerun on July 29, where we discuss how point and local operation filters can be used to control sources of error such as noise or low contrast in microscopy images. As well as exploring the mathematics behind image processing techniques such as segmentation, extraction and thresholding, our expert Heiko will also discuss the ethics of image processing – helping you judge whether specific techniques are allowed.

Digital Image Processing Part 2: Advanced Image Processing Filter
Thursday, 25 March, 2021
Experts
In our first webinar on this topic, we learnt that images taken with a light microscope are never quite a perfect reflection of our samples. There are always sources of error, and as we can only minimize such errors, the raw data of an imaging experiment will often need some digital image processing before final image analysis.

Images captured with a light microscope are never true representations of the specimen; there are always sources of error that must be controlled. In this webinar, we will discuss how these sources of error can be managed.
