This paper proposes an innovative approach for multi-objects recognition for homeland security and defense
based intelligent sensor networks. Unlike the conventional way of information analysis, data mining in such
networks is typically characterized with high information ambiguity/uncertainty, data redundancy, high
dimensionality and real-time constrains. Furthermore, since a typical military based network normally
includes multiple mobile sensor platforms, ground forces, fortified tanks, combat flights, and other resources,
it is critical to develop intelligent data mining approaches to fuse different information resources to
understand dynamic environments, to support decision making processes, and finally to achieve the goals.
This paper aims to address these issues with a focus on multi-objects recognition. Instead of classifying a
single object as in the traditional image classification problems, the proposed method can automatically learn
multiple objectives simultaneously. Image segmentation techniques are used to identify the interesting
regions in the field, which correspond to multiple objects such as soldiers or tanks. Since different objects
will come with different feature sizes, we propose a feature scaling method to represent each object in the
same number of dimensions. This is achieved by linear/nonlinear scaling and sampling techniques. Finally,
support vector machine (SVM) based learning algorithms are developed to learn and build the associations
for different objects, and such knowledge will be adaptively accumulated for objects recognition in the
testing stage. We test the effectiveness of proposed method in different simulated military environments.
