C.P. Loizou, C. Theofanous, M. Pantziaris, T. Kasparis, “Despeckle filtering software toolbox for ultrasound imaging of the common carotid artery”, Comput. Meth. & Progr. Biomed., vol. 114, pp. 109-124, 2014. Best paper, editor’s choice.

We proposed a despeckle filtering toolbox which includes also texture features analysis and extraction. Fourier Power Spectrum (FPS) can also be extracted from the images. The toolbox and the paper can be downloaded from researchgate. The code is in an executable form. You may also find additional coding and matlab functions in our website http://www.medinfo.cs.ucy.ac.cy/ under downlaods-->Toolboxes tab.

Hi Christos P Loizou

http://www.medinfo.cs.ucy.ac.cy/ this link is not working please send correct link

Dear Prabhakar. We are working to update the website. Please try in a few days again.

Maybe this matlab code is useful.
