A Single-Operator Push-Cart Multi-Beam LiDAR Platform for Multi-Trait Field Phenotyping [PDF]
Here, we present a single-operator push-cart platform equipped with a 16-beam LiDAR. A push-button interface controls data acquisition, and the data processing pipeline removes ground points, filters noise, performs 5-cm voxelization, and produces plot ...

Two-Threshold-Variable Integer-Valued Autoregressive Model
In the past, most threshold models considered a single threshold variable. However, for some practical applications, models with two threshold variables may be needed. In this paper, we propose a two-threshold-variable integer-valued autoregressive model
