I hate tinypic. While I do not see most probably the image you want us to show, I see a bunch of unrelated images and one of them has a sexual background.

It's absolutely crazy that the Mathworks still does not have a public place to upload pictures that we so often discuss here.

Lots of filters you could use, for example median filter (medfilt1), or Savitzky-Golay (sgolay), or simple averaging (conv), or more sophisticated ones like in SLM: http://www.mathworks.com/matlabcentral/fileexchange/24443-slm-shape-language-modeling or the Curve Fitting Toolbox.
