Finding Edge Features Using the Fast Level Set Transform and the Helmholtz Principle
Found in: Image Analysis and Interpretation, IEEE Southwest Symposium on
By Arjuna Flenner
Issue Date:March 2008
pp. 9-12
There is a need to develop automated methods to analyze images. A method that relies on the Helmholtz principle to discover edge features that is weakly dependent on the parameters is presented. An application of the Helmholtz principle requires a method o...
Multiclass Data Segmentation Using Diffuse Interface Methods on Graphs
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Cristina Garcia-Cardona,Ekaterina Merkurjev,Andrea L. Bertozzi,Arjuna Flenner,Allon G. Percus
Issue Date:August 2014
pp. 1600-1613
We present two graph-based algorithms for multiclass segmentation of high-dimensional data on graphs. The algorithms use a diffuse interface model based on the Ginzburg-Landau functional, related to total variation and graph cuts. A multiclass extension is...
