Image Data from ImageJ to R and Vice Versa

August 5, 2011
By

In recent years many R packages have been developed to enable image analysis in R. As an alternative the combination of R with a powerful image analysis software like ImageJ offers many advanced image analysis interfaces and algorithms not yet available in R. Bio7 integrates both applications in a Rich Client Plattform based on Eclipse

Shared Ecological Modelling References

June 6, 2011

05.06.2011 Today i started to create a list of books and articles about ecological modelling. In this list you will not only find general books about modelling but also books about spatial analysis, image analysis and other (in my opinion) important techniques useful in the context of ecological modelling. For the collection i use “Zotero”

Image Classification Limits Part 2

March 31, 2011
By

Recently i released the first 64-bit versions of Bio7 bundled with a 64-bit Java Virtual Machine. I’m always curious how far i can go using both applications together to do image analysis (especially classification) with huge images coming e.g. from satellites. The transfer of the images in Bio7 is realized with a combination of ImageJ

New R features in Bio7 1.5

Bio7 1.5 has been released and comes with new functionalities for R. For all who don’t know Bio7 here is a short description: Bio7 is a integrated development environment for ecological modelling based on the Rich-Client-Platform concept of the Java IDE Eclipse. The Bio7 platform contains several perspectives which arrange several views for a special

Image Data and Classification with R

August 3, 2010
By

03.08.2010 In this post i would like to demonstrate the ability of R to handle and classify image data with the help of ImageJ and Rserve bundled and implemented in Bio7. In general R is a very useful application for image analysis and plenty of “pure” R packages for image analysis are already available. But

Plots in R and the ImageJ visualization

If you plot data in R and you would like to display the same data in the ImageJ view it is necessary to transfer the data matrix to ImageJ. The first thing which can be noticed is that the image data is displayed rotated because of the Bio7 approach to transfer data forth and back

Ecological Modelling with “R”

March 7, 2010
By

Here i present some Books and Articles about Ecological Modelling and “R”. Since “R” is integrated in Bio7 all the presented methods in the Books and Articles can also be useful together with Bio7. Books: Ellner, Stephen P. & Guckenheimer, John (2006). Dynamic Models in Biology. Princeton University Press Bolker B (2008) Ecological Models and

Visualize dynamic data from R in 3d

February 17, 2010
By

In this video i demonstrate a nice feature of Bio7 to visualize 3d data created in “R” dynamically. The data for the points is generated in “R” and then transferred to the OpenGL view of Bio7. In the first example a random plot is generated and updated. In the second example 10000 random (lighted) spheres
