Fri, 5 Mar 2010: Back from VizBi at EMBL

Pavel Tomančák talked about microscopy and registration and I presented a poster about TrakEM2 and CATMAID.

Fri, 19 Feb 2010: Finished registration of Albert Cardona's fantastic ssTEM data set

The data set shows an abdominal segment of the VNC of a Drosophila first instar larva, that is a volume of 80×50×23μm in 459 serial sections of 50nm, overall 33,499 non-empty images at 4nm/px. Watch this movie to get an idea. While running this, I fixed several tiny bugs that were slowing down the process.

Sat, 30 Jan 2010: Visited Albert Cardona at INI for coding TrakEM2

The alignment of multi-layer mosaics can now calculate a smooth continuous deformation for each layer instead of just rotating and shifting the tiles. The amount of layer-deformation is adjustable through the weights of intra-layer vs. cross-layer point matches.

Have fun with my new website.

Thu, 26 Nov 2009: CLAHE plugin for Fiji/ImageJ

Added mask support to the CLAHE plugin. The dialog offers all images with the same dimensions as the current image as possible masks. Combining Rois and masks is possible and a powerful tool.

Sat, 14 Nov 2009: CLAHE plugin for Fiji/ImageJ

Inspired by the work of Pavel Koshevoy, we implemented the Contrast Limited Adaptive Histogram Equalization (CLAHE) as an ImageJ plugin and put it into Fiji. A manual page is available at the Fiji-Wiki.
