I am doing a project now about the Pinna and sound collection.I used photoscanner to get pictures of human pinnas and made them into a obj file, Now I am able to create the pointcloud and the triangular mesh. Because the pictures are not fully covering the pinna, some places exist holes and gaps. Right now I have the vertices information as well as the faces information in a structure.I am searching for some algorithm to automatically fill the holes. I found some articles about that but don't know how to apply it into Matlab. Can someone tell me how to use Matlab function to operate this? I found a package of iso2mesh files but don't know how to use them and some files run with error with my Matlab. Thanks for any help.

Dear Huichao, Could you solve the problem?
Look at the following code. I removed some faces. How can I fill the removed faces again?
vol = zeros(20,20,20); % Empty voxel volume
vol(8:12,8:12,5:15) = 1; % Turn some voxels on
fv = isosurface(vol, 0.99);
% REMOVE some face
fv.faces(30:31,:) = []; % Remove a face!
