Matrix-Structural Learning (MSL) of Cascaded Classifier from Enormous Training Set
Matrix-Structural Learning Cascaded Classifier Training Set
2010/12/17
Aiming at the problem when both positive and negative training set are enormous, this paper proposes a novel Matrix-Structural Learning (MSL) method, as an extension to Viola and Jones’ cascade learni...
