CPPP/UFMS at ImageCLEF 2014: Robot Vision Task
نویسندگان
چکیده
This paper describes the participation of the CPPP/UFMS group in the robot vision task. We have applied the spatial pyramid matching proposed by Lazebnik et al. This method extends bag-of-visualwords to spatial pyramids by concatenating histograms of local features found in increasingly fine sub-regions. To form the visual vocabulary, kmeans clustering was applied in a random subset of images from training dataset. After that the images are classified using a pyramid match kernel and the k-nearest neighbors. The system has shown promising results, particularly for object recognition.

This working note describes the method of the NUDT team for scene classification and object recognition in the ImageCLEF 2014 Robot Vision Challenge. The method is composed of two steps: 1. spatial pyramid match (SPM) and a Pyramid of HOG (Histograms of Oriented Gradient) are incorporated to represent an indoor place image. 2. a multiclass SVM (Support Vector Machine) is utilized to classify an...
