Solving Multi-Instance Visual Scene Recognition with Classifier Ensemble Based on Unsupervised Clustering

Abstract

This paper proposes a new image Multi-Instance (MI) bag generating method, which models an image with a Gaussian Mixed Model (GMM). The generated GMM is treated as an MI bag, of which the color and locally stable invariant components (SIFT) are the instances. Agglomerative Information Bottleneck clustering is employed to transform the MIL problem into single-instance learning problem so that single-instance classifiers can be used for classification. Finally, ensemble learningis involved to further enhance classifiers generalization ability. Experimental results demonstrate that the performance of the proposed framework for image recognition is superior to some common MI algorithms on average in a 5-category scene recognition task Key words:Multi-Instance Learning; Gaussian Mixed Model; AIB Clustering; image modeling; Single-Instance Bag; Ensemble Classifier; Scene Recognition
