Methods for identifying biomarkers present in biological tissues, medical imaging systems, and methods for training the medical imaging systems

A multispectral imaging system is trained by the application of an unlabelled multispectral image. Artificial labels are added to each image at corresponding wavelengths of the unlabelled multispectral image in view of training a machine learning system. Spatial and then spatial-spectral features of the multispectral images are extracted in successive training phases. The trained machine learning system may then be used to detect biomarkers or other artefacts in a multispectral image by splitting the multispectral image into distinct wavelength-images, applying masks to the wavelength-images to obtain pixel groups, applying statistical calculation to the pixel groups, assembling statistical calculation results into feature vectors, and using the trained machine learning system to extract, from the feature vectors, positive or negative indications related to the presence of biomarkers of other artefacts in the multispectral image.
