An Improved Top-Hat Filter with Sloped Brim for Extracting Ground Points from Airborne Lidar Point Clouds
Airborne light detection and ranging (lidar) has become a powerful support for acquiring geospatial data in numerous geospatial applications and analyses. However, the process of extracting ground points accurately and effectively from raw point clouds remains a big challenge. This study presents an improved top-hat filter with a sloped brim to enhance the robustness of ground point extraction ...
متن کاملExtracting Skeletons from Distance Maps
A skeleton is a useful shape descriptor that encodes both boundary and region information for a given object. A widely used approach for skeletonization is to use a distance transform. Although many skeletonization algorithms have been developed, most methods involve the computation of high order derivatives and the evaluation of complex expressions. In this paper, we propose an algorithm that ...
متن کاملResource allocation based on DEA for distance improvement to MPSS points considering environmental factors
This paper proposes a new resource allocation model which is based on data envelopment analysis (DEA) and concerns systems with several homogeneous units operating under supervision of a central unit. The previous studies in DEA literature deal with reallocating/allocating organizational resource to improve performance or maximize the total amount of outputs produced by individual units. In tho...
متن کاملFixed Points Theorems with respect to \fuzzy w-distance
In this paper, we shall introduce the fuzzyw-distance, then prove a common fixed point theorem with respectto fuzzy w-distance for two mappings under the condition ofweakly compatible in complete fuzzy metric spaces.
متن کاملMultichannel distance filter
A nonlinear multichannel digital filter is presented in this correspondence. The output is a weighted sum of all samples in the filter window, with a single parameter controlling the filter nonlinearity. Although input data ordering is not required, performance can surpass the performance of other ordering-based multichannel filters.
