1、Multispectral Image Database(哥伦比亚大学多谱图像数据库数据摘要：The database consists of 32 scenes, divided into 5 sections. Each scene has an associated zip file. These zip files include full spectral resolution reflectance data from 400nm to 700nm at 10nm steps (31 bands total. Each band is stored as a 16-bit gray

2、scale PNG image. Image filenames are of the format 'object_ms_01.png', where the '01' at the end signifies that this is the first image (captured at 400nm. Thus, '02' corresponds to 410nm, and so on, until '31' for 700nm.Each scene also contains a single representativ

4、ltispectral Image DatabaseWe present a database of multispectral images that were used to emulate the GAP camera. The images are of a wide variety of real-world materials and objects. We are making this database available to the research community. Details of the database can be found in the followi

As a result, each multispectral image should be taken as a close approximation, rather than exact measurement, of the true reflectance of t
