Large bande Multi-Spectral data based 400-1100 nm:
Application for Precision Agriculture
The multispectral image database of the University of Bourgogne Franche-Comté (UBFC) is an essential resource for researchers and students working in the field of image analysis and optical signal processing. It contains multispectral images captured under different lighting conditions and at different wavelengths, offering a wide range of potential applications from material analysis to remote sensing and medical diagnosis.

NOTE: These multispectral images represent the reflectances of plants and weeds present in the scene. The reflectance spectrum of each pixel was calculated from the multispectral image measured using calibrated estimates of the illumination spectrum and spectral response of the cameras in the visible and near infrared.
Database Organization
The database consists of plant and weed scenes. Each scene has full spectral resolution in 10nm increments (a total of 8 bands) and in the near infrared. Each band is stored as a 16-bit grayscale TIFF image.Each scene also includes a representative color image displayed using sRGB values rendered under neutral daylight illumination (D65).
