High-Definition Map Change Regions Detection Considering the Uncertainty of Single-Source Perception Data

Machines
High-definition (HD) maps, with their accurate and detailed road information, have become a core component of autonomous vehicles. These maps help vehicles with environment perception, precise localization, and path planning.

Monitoring of sawfl y ( Hymenoptera: Tenthredinidae Hymenoptera: Tenthredinidae ) infestation on spruce

Journal of Forest Science, 2002
A new method for evaluating damage caused by tenthredinids to Norway spruce stands is based on defoliation of the top whorls. A scale with four classes of defoliation was established that is easy to use. Defoliation can be displayed graphically on a grid

A feature based change detection approach using multi-scale orientation for multi-temporal SAR images

European Journal of Remote Sensing, 2020
Excellent operation regardless of weather conditions and superior resolution independent of sensor light are the most attractive and desired features of synthetic aperture radar (SAR) imagery.

Across the grain: Multi-scale map comparison and land change assessment

Ecological Indicators, 2016
Abstract Changes in the spatial distribution of land cover and land use can have significant impacts on ecological processes at multiple scales; estimating these changes provides critical data for both monitoring and understanding land-use effects on these processes.

The mass function and dynamical mass of young star clusters: Why their initial crossing-time matters crucially

, 2012
We highlight the impact of cluster-mass-dependent evolutionary rates upon the evolution of the cluster mass function during violent relaxation, that is, while clusters dynamically respond to the expulsion of their residual star-forming gas.

On the 2d Zakharov system with L^2 Schr\"odinger data

, 2009
We prove local in time well-posedness for the Zakharov system in two space dimensions with large initial data in L^2 x H^{-1/2} x H^{-3/2}. This is the space of optimal regularity in the sense that the data-to-solution map fails to be smooth at the ...
