Multispectral Cameras, Bayer Mosaics and Image Processing with MATLAB

When editing the images of the MAPIR Survey 2 NDVI camera, I learned a lot about how cameras actually capture and store images. The knowledge was important in order to properly import the images into MATLAB, process them and compute an NDVI image of them. If you do not do it right, you can see it immediately: You do not get a nice picture! Continue reading “Multispectral Cameras, Bayer Mosaics and Image Processing with MATLAB”

Which vector graphics software do you recommend to your students?

The excellent graphics capabilities of MATLAB make it virtually unnecessary to edit graphics with vector graphics software (see blog post “Create Publishable Graphics with MATLAB“). Only very occasionally we need such software, for example to edit graphics that have not been created with MATLAB. Which both commercial and free software do you recommend your to students for this? Continue reading “Which vector graphics software do you recommend to your students?”

Reading and Processing XrdML Files Storing X-Ray Powder Diffraction (XRD) Data With MATLAB

The XrdML file format is used to store X-ray powder diffraction measurements. Since XrdML format using the .xrdml file extension is an XML-based open file format using an ASCII format, reading such files with MATLAB is easy. Here is an example of reading multiple XrdML files from a file directory, convert the files in text files, display the measurements together with standard mineral data from a XRD data base.
