12 Sep 2012 Image Super-Resolution - Iterative Back Projection Algorithm A simple maximum-likelihood algorithm for super-resolution. Author: Victor May

When generating the stack of LowRes Images the code only produces a diagonal shift, since the offsets along x and y are identical.

change the following line in SynthDataset:

offsets(i,:)=2*rand -1 --> offset(i,:)=2*rand(2,1)-1

29 Jun 2011 Dynamic Low, High and Band pass filter An application to dynamically filter signal (sound) with interactive drag of mouse Author: Gaurav Gupta

very nice work.
One suggestion: left limit of the bandpass filter (green dot) is trapped, and cannot be controlled with the mouse, if you want to move it towards lower frequencies.

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

Hi,Petersen
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: 2110190101@email.szu.edu.cn. Thank you!
