Fig. 1From: Fully automated registration of vibrational microspectroscopic images in histologically stained tissue sectionsProblem overview. The FTIR image is a multi-spectral image where each pixel is represented by an infrared absorption spectrum (Five sample spectra shown). Typically, the FTIR microscopic image captures a small subregion of the complete H&E stained tissue section, turning the registration problem into a template matching problemBack to article page
