Image Capture InformationNOTE: These multispectral images represent the reflectances of the materials in the scene. The reflectance spectrum at each pixel was computed from the measured multispectrum image using calibrated estimates of the illumination spectrum and camera spectral response. As a result, each multispectral image should be taken as a close approximation, rather than exact measurement, of the true reflectance of the scene. |
Database OrganizationThe 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 grayscale 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 representative color image, displayed using sRGB values rendered under a neutral daylight illuminant (D65). |
Access InstructionsThe database of 32 scenes is divided into 5 sections, as below. It is also available as a single zip file [387 MB].Stuff Skin and Hair Paints Food and Drinks Real and Fake |

Joensuu Spectral Image Database This data is generally meant for our internal/student use and it has limited documentation. Still, anybody is free to use these data files.
