For the function 'detectSURFFeatures', I cannot get it to work because I am somehow using the wrong datatype. I have converted the image into all possible datatypes, but it is still not working. It is also already in greyscale. Please help.

Can you let me know what is the input to the 'detectSURFFeatures' in your case? What is the dimension of the input and do you get any error when you use the function?

Input: 648 x 1128 uint8 greyscale matrix

Error: Undefined function 'detectSURFFeatures' for input arguments of type 'uint8'.

Error in Laser_Finder (line 12) laserPoints = detectSURFFeatures(laser_Image,'NumOctaves',1);

It sounds like you may not have the Computer Vision System Toolbox installed. Or you may not have a license. Or you may have an older version. detectSURFFeatures was introduced in R2011b.
