摘要

高光谱照片处理(HIP)是一种用于识别和检查超维度记录集特征的分析方法。借助高光谱照片处理技术所面临的困难之一是存在噪声能力,这可能会使理解实际统计数据具有挑战性,并降低评估的准确性。有人提出了一种混合时间序列聚类技术,用于对有噪声的高光谱照片进行符号化和分类。这种方法将两种不同的聚类算法(自组织图(SOM)和分层聚类(HC))与信号压缩器(小波重塑(WT)和离散余弦变换(DCT))相结合,以发现和减少噪声。事实证明,这种方法比传统的高光谱照片处理方法具有更高的准确性。它还能实现更高的特征检测,并提供更准确的事实集表示,使研究人员能够更好地发现传统策略可能遗忘的微妙功能。

Utilizing Hybrid Time Series Clustering Algorithms for Hyper Spectral Image Processing
Hyperspectral photo processing (HIP) is an analytical method for recognizing and examining features in excessive-dimensional record sets. One of the demanding situations faced with the aid of HIP is the presence of noisy capabilities that may make it challenging to understand actual statistics and degrade the accuracy of the evaluation. A hybrid time series clustering technique has been proposed to symbolize and categorize noisy hyperspectral photos. This approach combines two different clustering algorithms (self-organizing map (SOM) and hierarchical clustering (HC)) with signal compressors (wavelet remodel (WT) and discrete cosine transform (DCT)) to come across and reduce noise. This approach has been proven to have better accuracy than traditional methods for hyperspectral photo processing. It also enables higher detection of features and offers a more accurate representation of the facts set, permitting researchers to higher hit upon subtle functions that conventional strategies may forget.
