With the continuous expansion of the use of mobile robots, providing them with autonomous navigation capabilities for different environments has become a very active research topic. In most cases, navigation systems are built around sensors like LiDAR which are expensive, not only due to the sensor cost but also to the computational power required for the processing of Point-Clouds. To provide an alternative to such systems, we propose a navigation approach that only requires a front-facing RGB Camera. In this system, every image is processed online using a semantic segmentation model to build a Bird's-Eye view semantic map, from which a local path and the corresponding motion commands can be calculated. Our method is evaluated first in simulation and later on, in a real mobile robot. The results show that our system enables the robot's successful navigation and collision avoidance through simulated and real indoor and outdoor environments.

Face anti-spoofing (FAS) aims to counter facial presentation attacks and heavily relies on identifying live/spoof discriminative features. While vision transformer (ViT) has shown promising potential in recent FAS methods, there remains a lack of studies examining the values of incorporating local descriptive feature learning with ViT. In this paper, we propose a novel LDCformer by incorporating Learnable Descriptive Convolution (LDC) with ViT and aim to learn distinguishing characteristics of FAS through modeling long-range dependency of locally descriptive features. In addition, we propose to extend LDC to a Decoupled Learnable Descriptive Convolution (Decoupled-LDC) for improving the optimization efficiency. With the new Decoupled-LDC, we further develop an extended model LDCformer(D) for FAS. Extensive experiments on FAS benchmarks show that LDCformer(D) outperforms previous methods on most of the protocols in both intra-domain and cross-domain testings. The codes are available at https://***/Pei-KaiHuang/ICIP23_D-LDCformer.
