一文详解高光谱数据python处理包spectral(SPy),解决方案:ASD(AnalyticalSpectralDevices)是一种用于地面光谱测量的设备,可以测量多个波长范围内的反射率。,然后保留足够的特征值
SPy 的imshow()函数是一个名字相同的matplotlib函数的包装。 主要区别在于,SPy版本可以很容易地显示来自多光谱/高光谱图像的波段,它呈现分类图像,并支持多种其他类型的交互性。 Image Data Display 的imshow函数产生与np.ndarray或SpyFile对象相关联的数据的一个光栅显示。
In Python, a single string expression can be evaluated asf(E,P), wherefis the evaluation function,Eis the expression to evaluate, andPis a dictionary of local variables that serve as inputs for undefined variables inE. Since\({E}_{\psi }\in {A}_{\psi }\)is a valid expression that ...
To perform the GP regression on light curves and spectra, we use the python packages george (Ambikasaran et al. 2015) and scikit-learn (Pedregosa et al. 2011), respectively. The former is less complex and faster, and works more efficiently with low-size data sets, while the latter handles...

To facilitate this, ProSPyX, a Python package that offers the analysis tools and a graphical user interface required to process spectral ptychography datasets, is presented. Using the PyQt5 Python open-source module for development and design, the software facilitates extraction of absorption and ...
Spectral Python (SPy) is a pure Python module for processing hyperspectral image data (imaging spectroscopy data). It has functions for reading, displaying, manipulating, and classifying hyperspectral imagery. Full details about the package are on theweb site. ...
影像方差的绝大部分被捕获到少数(相较于影像波段数)主成分中。 SPy 函数principal_components()计算影像的主成分,返回一个PrincipalComponents对象,它包含了均值、协方差、特征值和特征向量等数据。它也包含了一个将数据转换到主成分空间的方法,和一个减少特征向量的方法。 In [18]: pc = principal_components(img)...
一、基本操作读取高光谱数据文件 import spectral # 读取ENVI格式的高光谱图像 # image的后缀可以是.raw、.spe、.lan等 # 代码里img对象,类似于rasterio库的dataset对象,可以用它来读取高光谱数据 img = spectra…
