Uniform face meshes are able to represent the face in 3D format and can also be used to perform 3D face recognition.However, to obtain a good recognition rate, a fine mesh which consists of many points would be needed to accurately represent the many contours of the face.Therefore, in this paper, it is proposed that a non-uniform face mesh is constructed for 3D face recognition. A non-uniform mesh consisting of fine meshes for the middle of the face and coarse meshes for the rest of the face was created. In comparison with a uniform mesh, the proposed non-uniform face mesh consists of much fewer points and therefore saves storage space and transmission time due to a smaller file size.Besides that, the proposed mesh was able to produce recognition rates that were only slightly lower than the uniform mesh, hence proving that important face features for recognition were retained.
