2D Rotated Gaussian Fit



Function will fit a 2D gaussian function. It will also find the rotation angle for the 2D gaussian.

File Information

Matlab's Surface fitting does not (yet) include fairly standard defined surfaces. The present contribution is a simple implementation of the surface fit to the problem of fitting a 2D gaussian to an observed object in an image. Keep the image size small in order not to suffocate the fitting routine.

Gauss2DRotFit requires an input in the form of a 2D intensity image of the 2D gaussian. It also accepts as a second input an structure defining the lower, upper bounds as well as a best guess of the 7 fit parameters. The structure has 3 fields: 'Lower','StartingPoint' and 'Upper'. A title string may be provided as a third input parameter.

what do you mean by 'Lower', 'StartingPoint' and 'Upper'?

I have read the code and find it very good. But now I do have some problem in calling the function.By more details, I do not know the data-style of 'im' in your code and the meaning of 'varargin'. So could you give me a example of calling the function. If it is convenient by email, please inform me. By the way my email is: Thank you!
