RT Journal Article T1 Robust and Fast Scene Recognition in Robotics Through the Automatic Identification of Meaningful Images A1 Santos Saavedra, David A1 López López, Eric A1 Pardo López, Xosé Manuel A1 Iglesias Rodríguez, Roberto A1 Barro Ameneiro, Senén A1 Fernández Vidal, Xosé Ramón K1 Scene recognition K1 Image collection summarization K1 Meaningful images AB Scene recognition is still a very important topic in many fields, and that is definitely the case in robotics. Nevertheless, this task is view-dependent, which implies the existence of preferable directions when recognizing a particular scene. Both in human and computer vision-based classification, this actually often turns out to be biased. In our case, instead of trying to improve the generalization capability for different view directions, we have opted for the development of a system capable of filtering out noisy or meaningless images while, on the contrary, retaining those views from which is likely feasible that the correct identification of the scene can be made. Our proposal works with a heuristic metric based on the detection of key points in 3D meshes (Harris 3D). This metric is later used to build a model that combines a Minimum Spanning Tree and a Support Vector Machine (SVM). We have performed an extensive number of experiments through which we have addressed (a) the search for efficient visual descriptors, (b) the analysis of the extent to which our heuristic metric resembles the human criteria for relevance and, finally, (c) the experimental validation of our complete proposal. In the experiments, we have used both a public image database and images collected at our research center PB MDPI YR 2019 FD 2019 LK http://hdl.handle.net/10347/21247 UL http://hdl.handle.net/10347/21247 LA eng NO Santos, D.; Lopez-Lopez, E.; Pardo, X.M.; Iglesias, R.; Barro, S.; Fdez-Vidal, X.R.
