Sažetak
Visual place recognition aims to identify previously visited locations from image representations that are robust to viewpoint and environmental changes. Deep convolutional neural network features perform well for this task, yet they are typically pretrained for classification or segmentation – objectives that do not account for the sequential nature of place recognition. In mobile robotics, exploiting image sequences can further improve performance. We propose softmax-based fine-tuning of a convolutional network extended with a recurrent model to enhance place recognition on image sequences. Experiments on two public datasets show that the proposed representation consistently outperforms competing approaches across all evaluated methods.
