Undefined function or variable 'shapeMU'

my requirement is to convert 2d face image to 3d face image

The following is the code to read the image and convert to 3D

ndims = 50; numsd = 0.5; addpath('BoundaryVertices','RamananDetector','Functions','SOP'); BFMbasedir = 'E:\PublicMM1\02_scans_matlab\'; load(strcat(BFMbasedir,'00001_20061015_00418_neutral_face05.mat')); load('BFMedgestruct.mat') landmarks=[8333,7301,6011,9365,10655,8320,8311,8286,8275,5959,4675,3642,4922,3631,2088,27391,39839,40091,40351,6713,10603,11641,12673,11244,12661,14472,27778,41804,41578,41310,9806,8345,7442,6936,5392,7335,7851,8354,9248,9398,11326,9399,9129,9406,9128,8890,8367,7858,7580,7471,8374,23002,32033]; im = imread('pie.png'); xp= RamananDetector(im); shapePC=pca(xp); % this method is used to get the principal components, pls correct if i am wrong [b,R_est,t_est,s_est] = FitEdges( im,xp,landmarks,shapePC,shapeMU,shapeEV,Ef,Ev,tl,ndims,numsd );

I need your help to define the variable ShapeMU, ShapeEV, ef, Ev & t1

FYI: ShapeMU is 3n by 1 vector containing the vertices of the mean shape. How to get vertices from mean shape shapeEV is a k by 1 vector containing the sorted standard deviations of each principal component. Pls let me know how to achieve the same.

Pls suggest with a possible solution

Thanks vijay
