Samson是一个简单的图像数据集，可从[网站](http://opticks.org/confluence/display/opticks/Sample+Data)获取。该图像包含952x952像素，每个像素记录了156个通道的光谱数据，波长范围从401 nm到889 nm，光谱分辨率高达3.13 nm。由于原始图像过大，计算成本高，因此使用了从原始图像中截取的95x95像素区域，起始于原始图像的第(252,332)个像素。该数据集未受到空白通道或严重噪声通道的影响，并包含三个目标：#1 Soil、#2 Tree和#3 Water。

Samson is a simple dataset that is available from the [website](http://opticks.org/confluence/display/opticks/Sample+Data). In this image, there are 952x952 pixels. Each pixel is recorded at 156 channels covering the wavelengths from 401 nm to 889 nm. The spectral resolution is highly up to 3.13 nm. As the original image is too large, which is very expensive in terms of computational cost, a region of 95x95 pixels is used. It starts from the (252,332)-th pixel in the original image. This data is not degraded by the blank channel or badly noised channels. Specifically, there are three targets in this image, i.e. #1 Soil, #2 Tree and #3 Water respectively.
