A method for generating a machine learning model for identifying or classifying biological structures depicted in a base image, comprising: obtaining a first training dataset, the first training dataset including first sets of coregistered images of biological structures, each first set including a first base image and a first informer image, and being associated with first label data; training, using the first training dataset, a label generation model, the label generation model configured to accept as input a second set of coregistered images and to produce as output second label data corresponding to the second set of coregistered images, the second set of coregistered images including a second base image and a second informer image; generating a second training dataset using the label generation model, the second training dataset including the second base images and the second label data; and training, using the second training dataset, a classification model configured to accept as input a third base image without additionally accepting a corresponding informer image as input, and to provide as output an indication when a biological structure is identified or classified in the third base image; wherein the base image and its respective informer image are of the same biological material, the informer image contains complementary information on the biological material which is absent from its respective base image or the informer image emphasizes or highlights information present in its respective base image, wherein the first label data, the second label data, or the indication comprises at least one of: a graphical effect overlaid on the first base image, the second base image, or the third base image, respectively; a graphical indicator or alphanumeric label associated with the first base image, the second base image, or the third base image, respectively; or one or more coordinates indicating locations of biological structures in the first base image, the second base image, or the third base image, respectively. obtaining a first training dataset, the first training dataset including first sets of coregistered images of biological structures, each first set including a first base image and a first informer image, and being associated with first label data; training, using the first training dataset, a label generation model, the label generation model configured to accept as input a second set of coregistered images and to produce as output second label data corresponding to the second set of coregistered images, the second set of coregistered images including a second base image and a second informer image; generating a second training dataset using the label generation model, the second training dataset including the second base images and the second label data; and training, using the second training dataset, a classification model configured to accept as input a third base image without additionally accepting a corresponding informer image as input, and to provide as output an indication when a biological structure is identified or classified in the third base image; wherein the base image and its respective informer image are of the same biological material, the informer image contains complementary information on the biological material which is absent from its respective base image or the informer image emphasizes or highlights information present in its respective base image, wherein the first label data, the second label data, or the indication comprises at least one of: a graphical effect overlaid on the first base image, the second base image, or the third base image, respectively; a graphical indicator or alphanumeric label associated with the first base image, the second base image, or the third base image, respectively; or one or more coordinates indicating locations of biological structures in the first base image, the second base image, or the third base image, respectively. a graphical effect overlaid on the first base image, the second base image, or the third base image, respectively; a graphical indicator or alphanumeric label associated with the first base image, the second base image, or the third base image, respectively; or one or more coordinates indicating locations of biological structures in the first base image, the second base image, or the third base image, respectively.
