Thresholding converts an image into a binary image, with pixel values of 0 or 1. This process works by setting to 1 all pixels whose value falls within a certain range, called the threshold interval, and setting all other pixel values in the image to 0. Figure 5a shows a grayscale ...
An instance-based learning approach for thresholding in crop images under different outdoor conditio 这篇文章主要是为了解决包含作物行的图像灰度化后,二值化所需阈值的选择问题。 作者主要利用k-means算出训练集中与之在概率累积图上相近的k幅图,然后将这些图的阈值乘以相应的权重获得目标图的二值化阈值。 作...
complex and time-consuming. Image processing software is used here, replacing manual analysis with an automated process. This reduces user influence and minimizes the time required to obtain information. Image analysis can work in connectivity with gray value analysis (thresholding) or via AI-based ...
