Does anyone have some idea on how I could convert the ultrasound image to the non-uniform mesh shown in the attachment? Any software or algorithm would do that? The region of the scatterer in the ultrasound image is more densely meshed. The software would have this intelligence to do it.

Thx.

Hello,

if you have your left image saved as a text file with (x,y) pairs (pixels positions ?) I suppose you can load it in Matlab and use some of the Delaunay mesh generators. This will give you a mesh made by triangles. What you have in the right picture seems to be a picture with the so called dual-mesh, this can be obtained by uniting the centers of gravity for the triangles that shares a point.

(If you need more details send me a private message and I will give you my email address.)

Hope this will help,

Do
