Every year, the floating macroalgae, green and golden tide, are massively detected at the Yellow Sea and East China Sea. After influx of them to the aquaculture facility or beach, it occurs enormous economic losses to remove them. Currently, remote sensing is used effectively to detect the floating ...

AlexNet 신경망은 무엇으로 구성된 구조인가? | AlexNet 신경망은 Input layer, Convolution layer, Pooling layer, ReLU layer, Fully connected layer, Softmax layer, Output layer 등 25개의 계층(layer)으로 구성된 구조(architecture)이다. 계층을 구성하는 뉴런(neuron)은 전이 학습 과정에서 입력된 학습 데이터에 대해 얼마나 일치하는지 가중치를 결정하며, 이에 따른 오차를 결정하여 학습하게 된다. | |
황해와 동중국해 연안은 원격탐사 영상에서 부유조류를 정확하게 탐지하는데 제약이 있는데, 그 이유는 무엇인가? | 또한 양자강 하구 유출수로 인하여 탁도가 매우 높으며, 어업활동이 활발하여 크고 작은 선박이 존재한다. 높은 탁도와 복잡한 탐지 대상들이 혼재되어 있어 원격탐사 영상에서 부유조류를 정확하게 탐지하는데 제약이 있다. 그러므로 이 연구에서 제시하는 부유조류 탐지 및 구분 방법의 성능을 평가하기 위해 이 해역을 연구지역으로 선정하였다. | |
Gaofen-1 위성의 특징은 무엇인가? | 본 연구에서는 Gaofen-1 위성에 탑재된 WFV 센서영상을 이용하여 딥러닝 학습 및 분석에 필요한 데이터셋을 구성하였다. Gaofen-1 위성은 중국우주국(China National Space Administration, CNSA)에서 2013년 4월에 발사한 위성이며, 탑재된 WFV 센서의 촬영 영상은 16m의 공간해상도를 갖는 3개의 가시광선 밴드(적색, 녹색, 청색)와 1개의 근적외선(Near Infrared, NIR) 밴드로 구성되어 있다(Table 1). |
