Symmetry • Find points with shape edges using different threshold angles
Computer symmetry plane My method Previous pose normalization
Problems • A better way to do cluster? • How to evaluate matching clusters more properly • Now using Gaussian mixture distribution • The covariance matrices are restricted to be diagonal • The distance score
Next • Use other feature points ( find the points by learning ) • Use features along with (x,y,z) to do clustering • Find 10 hard/easy ones in Cleft dataset • Prepare points (Giving examples) • Schedule a meeting with Michael • Triangles are more reliable (distance to be large) • Get manual landmarks from Jiun-hong’s
Jiun-hong’s pose normalize method • On automatic landmarks_> should be nice
Ideas • Bipartite matching • Fit clusters into lines • The use of bounding box • Corners of 3D • Use front and back info as a constrain • How to evaluate the results
Using position, such as exhausting searching, can do symmetry and find matching points back and forth a couple of times
Learn: what is a good matching!! • Give it some heads, learn from samples, what’s “good” matches • Instead of use self’s constrains
