Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.

Please pay attention to the main LHS mailing list or pop into our #london-hack-space IRC channel and say hello.

During this interim period donations and continued membership are greatly appreciated while we transition to our new space.

Image Focus Stacking

From London Hackspace Wiki
Jump to: navigation, search

Focus stacking is a process by which images with very shallow depth of field can be combined such that the final image is a composite of a series of images, where the final image only contains sections that are in focus for each of the source images.

A good tutorial on implementing focus stacking in linux is given in this blog post;

There is a wikipedia article on focus stacking;

It's possible to stack images from microscopes taken by adjusting the platform height, and moving different parts of the sample into the focal plane. This is called z-stacking.

I am looking to create a platform, using parts from a 3d printer, to automate creating z-stacked photomicrographs using a cheap ole' researcher microscope.
