Comparing Pixel- and Object-Based Approaches in Effectively Classifying Wetland-Dominated Landscapes
Remote Sensing, 2017 Wetland ecosystems straddle both terrestrial and aquatic habitats, performing many ecological functions directly and indirectly benefitting humans. However, global wetland losses are substantial.

WIREs Water, Volume 12, Issue 3, May/June 2025.A five‐step integrated modeling framework combines remote sensing and two‐dimensional hydraulic modeling to describe mesohabitats and assess suitability for target species. Remote sensing provides a Digital Terrain Model and an orthophoto (step 1) that can be used to classify and map environmental descriptors such as substrate and refugia (step 2).

A Fast Implementation of the ISODATA Clustering Algorithm
, 2005 Clustering is central to many image processing and remote sensing applications. ISODATA is one of the most popular and widely used clustering methods in geoscience applications, but it can run slowly, particularly with large data sets.

ISODATA: Thresholds for splitting clusters
, 1972 The author has identified the following significant results. The parameter AD (average distance) as used in the ISODATA program was critically examined. Thresholds of AD to decide on the splitting of clusters were obtained.

Gaoya dianqi, 2006 模糊ISODATA算法在基于变压器DGA的故障诊断中存在一些问题。如:模式空间的划分缺乏依据,聚类分析时没有考虑各种气体成分对故障反映的灵敏度等。笔者对此进行了改进,引入了一个描述不同气体成分对故障反映灵敏度的指标权向量,并在每次迭代运算之后对聚类中心进行分解和合并处理。利用改进的ISODATA算法对3起变压器故障进行了分析,得到了比较高的判断准确度。

Application of an improved ISODATA method to pipeline leak detection
Petroleum Science, 2007 Increasingly serious leak problem in pipeline transportation has not only affected the operation of pipelines but also caused loss of precious resource and environmental damage. Based on the analysis of the occurrence of negative pressure waves and the unsupervised learning of pattern recognition, the Interactive Self-organizing Data Analysis Technique
