Pixelsurfer

Framework for pixel surfing time series data. Ideal for MR and PET tracer data.

The GUI provides a general platform for 4D data exploration. It allows the user to pixesurf the image data and see the vector data for each pixel with instant update. For instance for PET or MR tracer data.

The GUI is a free floating viewport not connected to the plot allowing for more flexibily, eg. double screen support.

The GUI is ment as a sceleton for specialized development. It has little use but mere visual data exploration in the form presented here.
The viewport can be rescaled by the user, and is adjusted to be scaled by integer factors by a resize function.

The code is easily readable and only consists of 300 lines (Including the GUI template).An MR datafile (*.mat) is provided.

type:
>>load mydata8bit
>>pixelsurfer(mydata8bit) to try it out.

Data is in format:
mydata(row,column,timepoint,slice)
The dimension displayed as a vector is the timepoint dimension.
