Progress Report: Week 7
Alvaro Velasquez
Accomplishments
Learned a dictionary for the cuboids using KSVD.
Obtained a sparse coefficient matrix using sparse coding with graph regularization (This is the same framework that was used for the tracking in previous presentations).
Clustered cuboids into 6, 8, and 20 clusters using kmeans.
6 Clusters
8 Clusters
20 Clusters
Work for this Week
Further exploit the geometry of the image volume by choosing the initial cluster centroid locations using a max voting scheme on the sparse coefficient matrix.
Apply framework to a sequence of temporal blocks (We are currently using a single temporal block consisting of 4 frames).
