Calculate the area of green leaves using the vegetation index and the area of red leaves using the a-axis of the Lab color space using ImageJ (植生指数を用いて緑葉、Lab色空間のa軸を用いて赤葉の面積を算出する)

The vegetation index is an indicator used to quantify the vigor of vegetation and has been used for monitoring vegetation using remote sensing. This index can be used to extract green leaves from an image. For example, there is a vegetatio…

Each organ measurement and digital number extraction using ImageJ (ImageJを用いて各器官ごとに測定と画素値の収集を行う)

Here, how to output area, length, and width information, as well as the average pixel value for each organ from images using ImageJ is introduced. For example, leaf area is needed to calculate the Leaf Area Index (LAI), the area of leaves …

How to clip images from a video at regular intervals automatically(動画から一定間隔で画像を自動で切り取る方法)

Reconstructing a 3D model using aerial drone images requires taking images with a certain degree of overlap (80-90%) between neighboring images. Automatic flight applications that collect images with a set overlap ratio are useful, but som…

For EfficientNet implementation in neural network console

The paper proposed EfficientNet didn't aim to develop a specific network architecture but a method to scale up a certain model with taking a balance among width, depth, and resolution. However, the model architecture proposed by the author…
