Progress in high‐resolution numerical weather prediction (NWP) for urban areas will require new modelling approaches and extensive evaluation. Here, we exploit land surface temperature (LST) data from Landsat‐8 to assess 100 m resolution NWP for London (UK) on four cloud‐free days. The LST observations are directional radiometric temperatures with non‐negligible uncertainties. We consider the challenges...
Semantic integrity constraints represent knowledge about data with which a relational database must be consistent. To enforce semantic integrity we must ensure that transactions which alter the database will preserve database consistency by accompanying each transaction with integrity tests. In this paper we address two problems. Firstly, how can we choose integrity tests that are correct and efficient?...
Face detection is one of the most active research areas in computer vision. Despite the well documented success of classical machine learning techniques in controlled situations, face detection in completely uncontrolled settings remains a difficult task. Recent progress with bio-inspired approaches have addressed challenging areas of invariance including scale, occlusion and illumination issues,...
