In this paper we address visual based localization in outdoor environments where the appearance changes dramatically. Such environmental changes result in a substantial transformation of the visual information of the scene, producing a significant impact on the visual based localization performance. Hence, these changes can lead to major difficulties when associating data between the current image and the landmarks in the map. One solution for this problem is to keep adding landmarks to the map in order to cover various environmental conditions. However, this solution leads to a continued growth of the map, which in turn, will result in a costly and resource-intensive localization. In this paper we present a map management approach in which we exploit information related to the suns position to compare resemblance between the traversals in the map and maintain a diverse map that incorporates a minimum amount of data and ensures a reliable localization in different environmental conditions. We evaluated our approach on a dataset that incorporates more than 100 sequences with different environmental conditions and we compared the obtained results with a state of the art approach.
The article is devoted to the lossy compression of noisy images, considering the currently popular trend of green computing. In this paper, we show how this trend can be incorporated into solving an essential task of ...

In recent years, neural signed distance function (SDF) has become one of the most effective representation methods for 3D models. By learning continuous SDFs in 3D space, neural networks can predict the distance from a given query space point to its closest object surface, whose positive and negative signs denote inside and outside of the object, respectively. Training a specific network for each 3D model, which individually embeds its shape, can realize compressed representation of objects by storing fewer network (and possibly latent) parameters. Consequently, reconstruction through network inference and surface recovery can be achieved. In this paper, we propose an SDF prediction network using explicit key spheres as input. Key spheres are extracted from the internal space of objects, whose centers either have relatively larger SDF values (sphere radii), or are located at essential positions. By inputting the spatial information of multiple spheres which imply different local shapes, the proposed method can significantly improve the reconstruction accuracy with a negligible storage cost. Compared to previous works, our method achieves the high-fidelity and high-compression 3D object coding and reconstruction. Experiments conducted on three datasets verify the superior performance of our method.

The emergence of trillion-parameter models in AI, and the deployment of dense Graphics Processing Unit (GPU) systems with high-bandwidth inter-GPU and network interconnects underscores the need to design efficient architecture-aware large message communication operations. GPU-based on-the-fly compression communication designs help reduce the amount of data transferred across processes, thereby improving large message communication performance. In this paper, we first analyze bottlenecks in state-of-the-art on-the-fly compressionbased MPI implementations for blocking as well as non-blocking point-to-point communication operations. We then propose efficient point-to-point designs that improve upon state-of-the-art implementations through fine-grained overlap of copy, compression and communication operations. We demonstrate the efficacy of our proposed designs by comparing against state-of-the-art communication runtimes using micro-benchmarks and candidate communication patterns. Our proposed designs deliver 28.7% improvements in latency, 49.7% in bandwidth, and 36% in bidirectional bandwidth using micro-benchmarks, and up to 16.5% improvements for 3D stencil-based communication patterns over state-of-the-art designs.
