Image Classification Using PSO-SVM and an RGB-D Sensor

Abstract EN

Image classification is a process that depends on the descriptor used to represent an object.

To create such descriptors we use object models with rich information of the distribution of points.

The object model stage is improved with an optimization process by spreading the point that conforms the mesh.

In this paper, particle swarm optimization (PSO) is used to improve the model generation, while for the classification problem a support vector machine (SVM) is used.

In order to measure the performance of the proposed method a group of objects from a public RGB-D object data set has been used.

Experimental results show that our approach improves the distribution on the feature space of the model, which allows to reduce the number of support vectors obtained in the training process.
