CS194-26 Project 4

The Midway face is the averaging of both the geometric shape and the color of two faces. First thing I did was found the corresponding points which for me were 50 points around the face and contained eyes, nose, eyebrows, mouth. Then once we have the two sets of point, I did a Delaunay Triangulation on the midpoints -- which implies taking the two points and averaging them. This mean that the points had to be created in a corresponding manner or else this broke. Then using the delaunay triangulation, we coumpute the affine matrix from [x, y, 1] to [x', y', 1]. The affine matrix can be solved since we have 3 separate points on the triangulation that we can solve for. Once we find the affine matrix, we use the inverse of that times the destination pixel to find the source pixel -- which is an inverse warp.

I parsed through the asf files to find the facial points that they used on each face, then I found an average shape. I weighted each face equally, then cross-dissolving them together to form the average face of the entire population represented in the set - in this case, a set of 37 Danes -- however I took out the females. A few of the individual faces warped to the average geometry:

By warping my face away from the average Danes' geometry instead of toward it, I created caricature images that exaggerate the unique features of my face. I did around -.5 for this one and it looks quite strange!
