End-to-end autonomous driving has made significant advancements in these years. Efficiently fusing multi-modal sensor information to enhance the scene understanding capability and motion planning performance of end-to-end models is currently a prominent research topic.

A self-attention mech...Show More
Accurate ego-centric localization assumes a paramount significance in the domain of autonomous driving. However, traditional methods for camera-LiDAR map localization rely on perspective projection to create a unified representation, which often falls short due to challenges such as occlusion and the sparse nature of point cloud data. Despite the recent surge in popularity of the Bird’s-Eye-View (...Show More

Multimodal feature fusion representation, e.g., hyperspectral image and light detection and ranging (HSI-LiDAR) fusion, is an essential topic for fusion perception. However, existing networks tend to employ mandatory feature stacking or local context fusion strategies between multiple modalities, ignoring the power of globally mutual-guided feature transmission. Therefore, this paper develops a mu...Show More
Existing LiDAR odometry strategies match a new scan iteratively with previous fixed-pose scans, gradually accumulating errors. Furthermore, as an effective joint optimization mechanism, bundle adjustment (BA) cannot be directly introduced into odometry due to the intensive computation of global landmarks. Therefore, this paper designs a landmark map for bundle adjustment odometry (LMBAO) in LiDAR ...Show More
Preferential attachment, also referred to as the “rich-get-richer” mechanism, characterizes the ability of already existing nodes in an evolutionary network to acquire new connections from newly-coming nodes throughout the growing process of the network. This mechanism is responsible for the emergence of some critical structures in many real networks, such as the Saccharomyces cerevisiae protein-p...Show More
Body weight, as one of the biometric traits, has been studied in both the forensic and medical domains. However, estimating weight directly from 2-D images is particularly challenging since visual inspection is rather sensitive to the distance between the subject and camera, even for frontal view images. In this case, the widely used body mass index (BMI), which is associated with body height and ...Show More
