Point cloud data has been one type of widely used data sources in the field of remote sensing. Key steps of point cloud data’s pro-processing focus on gross error elimination and quality control. Owin...
In the present study, we applied the Particle Swarming Optimization (PSO) procedure to parametrize two Local Maxima (LM) algorithms and a pattern recognition model based on raster and point-cloud data...
Tree detection and tree crown delineation from Airborne LiDAR has been focusing mostly on utilizing the canopy height model (CHM). This paper presents a method for individual tree crown delineation ...
In this paper, a new method for estimation of vertical leaf area density (LAD) profile of tree canopy using portable scanning lidar is proposed. In this method, which we refer to as the voxel-based ...
This project has two main purposes; the first is to perform deciduous-coniferous classification for 65 trees by using the leaf-on single flight LiDAR data. It was done by looking at the geometrical ...
The study highlights a novel method to segment single trees in 3D from dense airborne full waveform LIDAR data using the normalized cut segmentation. The key idea is to subdivide the tree area in a vo...
LIDAR is an application widely open as an area of study for modelling detailed topographic maps. It is generally used in airborne applications. In this study, the aim is tree extraction from a data ha...
IN SPITE OF THEIR SPEED ADVANTAGE, carry save adder trees (CSA or Wallace trees’ ) are seldom, if ever, used in the design of monolithic multipliers. The main reason is the general belief that they ar...
Urban forests are important as valuable green resources to give moisture and tranquillity of mind in our living, requiring an efficient control of forest increase/decrease and growth rate. In this s...
Forest inventories collect feature data manually on terrestrial field plots. Measuring large amounts of breast height diameters and tree positions is time consuming. Terrestrial laser scanning could b...
In this paper an efficient speaker identification (SpkID) method is proposed. In GMM-based speaker recognition, the model training and the likelihood score computations are very time...
Bag-of-visual Words (BoW) image representation is getting popular in computer vision and multimedia communities.However, experiments show that the traditional BoW representation is not as effective as...
ZigBee技术的无线传感器网络是基于分布式地址分配的一种支持拓扑变化、节点移动的新型无线传感网络,拥有强大的自组网能力。针对ZigBee网络的Cluster-Tree算法对簇首能量要求高及节点间非最佳路由的问题,结合节点能量分析提出新的簇首产生办法,并结合AODVjr算法的思路来寻求节点间的最佳路由。仿真结果表明,改进的算法能够有效地提高数据发送成功率,降低网络中的死亡节点数,减小端到端的报文传...
High density airborne LiDAR, for example FLI-MAP 400 data, has opened an opportunity for individual tree measurement. This paper presents a method for individual tree delineation and undergrowth veg...
