his paper studies the extraction of power line in aerial image based on the Hough transform method. In the detection of Hough transform, it is easy to be interfered by the noise, which leads to false detection. Considering the characteristic of power line in aerial images, we propose a set of threshold based on Hough transform line detection results...

Abstract Mobilisation of iron in building stone due to acid rainfall and chemical cleaning may cause its uneven precipitation, discoloration of the stone and the formation of an indurated iron-cemented surface crust. Breaching of the crust can result in accelerated internal excavation, by, for example, salt weathering. Therefore, to understand the decay of iron-rich sandstone, the conditions ...
