Removing background noise

Hi,

I have been trying to remove background noise from a picture but the attempts I have made so far didn't really work.

I am trying to convert this picture:

Image

To something similar to this:

Image

I have tried -despeckle but didn't do much. I am using ImageMagick in Linux.

Does anyone know how I could approach this problem?

Thank you!

Hi, thanks for the quick reply! Texture analysis? I will have a look into that, it might be possible with other software, thanks!
But would there be any other solutions using ImageMagick?, I prefer using it....

I cannot think of any way other than manual tracing to create a mask and then composite the mask with the image to get the part you want.
