작물 분류에서 사용하는 원격탐사 자료의 종류는? | , 2017). 원격탐사 자료를 이용한 작물분류에는 MODIS, Landsat 등 중저해상도의 위성영상과 초고해상도의 무인기(UAV) 영상 등 다양한 원격탐사 자료가 활용되고 있다(Park and Park, 2015; Lee et al., 2016; Hall et al. | |
원격탐사 분야에서 기계학습 알고리즘과 딥러닝 알고리즘의 분류 성능을 비교하는 연구에는 무엇이 있는가? | 이와 관련하여 원격탐사 분야에서도 기계학습 알고리즘과 딥러닝 알고리즘의 분류 성능을 비교하는 연구가 다수 진행되고 있다. 대표적으로 기계학습 알고리즘에 SVM과 RF를 적용하고, 딥러닝 알고리즘에 2D-CNN과 3D-CNN을 적용하여 분류 결과의 정확도 및 공간양상 등을 바탕으로 분류 성능을 비교하였다(Song and Kim, 2017; Wu and Prasad, 2017; Liu et al., 2018; Zhong et al. | |
작물분류를 위한 분류 기법으로 주로 사용된 것은? | 작물분류를 위한 분류 기법으로 support vector machine(SVM), random forest(RF) 등의 기계학습 알고리즘이 주로 적용되어 왔으며(Kwak et al., 2017; Onojeghuo et al., 2018; Torbick et al., 2018; Xu et al., 2018), 최근 기계학습 알고리즘과 함께 딥러닝 알고리즘이 많이 적용되고 있다(Kussul et al., 2017; Kamilaris and Prenafeta-Boldú,2018). |
