Hi!
Both seem to be very interesting, I will definitely have a look. But maybe I 
should explain a little bit more what I need to do. I am not interested so 
much in the image chain that is applied to a raw image from a camera source. 
I am working with camera modules that have raw output, there is almost no 
image processing applied within the module. I have to analyze the images for 
defects and problems of the sensor, the optics and the interaction of both. 
Typical tasks are for example:
- Find the optical center from a homogeneously illuminated image
- Find specific target structures in the image and try to extract a sharpness 
measure
- Develop an algorithm that allows to quantify dust and flare
- Analyze typical optical problems like distortion, chromatic aberration, 
vignetting
- Analyze color shift problems caused by mismatch between sensor and optics / 
sensor settings
- Retrieve different metrics for several regions of interest on the image like 
color offsets, statistical measures, contrast...

All the processing performed on the image later on is quite interesting to me, 
because I need to take the influence of the image pipe on the final result 
into account. But my focus is really on the analysis of large matrix data 
sets. Typically I need 2D matrices for analysis of luminance values only, 3D 
matrices for analysis of RGB data. I also need 4D matrices for analysis of 
color data from raw images (in most image sensors, the color information is 
encoded by having a different color filter on each pixel, and later on 
retrieving a full RGB value for a pixel by interpolating the color 
information from neighbouring pixels).

So it is really rather data analysis of very differerent data sets , it only 
happens to be mostly imaging related at the moment.
