Do you have any suggestion about how to do it in a simpler case, which is the one of an average on a line profile with a generic orientation, which means oblique with respect to the x-y square axis reference of a 2d matrix? > Graphic library often calls for algorithm that turns-on a set of pixels on the screen that approximates a straight line between two given points. This kind of algorithm can be used, but it contains sort of complex looping, and may be too cumbersome for Matlab implementation. I have done that in my youth. You would be better stick with the generic method I have provided earlier. Bruno |
