Method for narrow-band image generation

Abstract

A method for narrow-band image generation is provided. First obtaining an input image of an object by an image capture unit. Then converting the input image according to an image conversion model and at least one target wave band corresponding to a narrow-band light source to get a simulated narrow-band image. Lastly comparing a simulated narrow-band image information of the simulated narrow-band image with a reference narrow-band image information according to at least one objective similarity index to generate an index data for determining similarity between the simulated narrow-band image information and the reference narrow-band image information. Thereby the simulated narrow-band image is checked by the objective similarity index combined with simulation of narrow-band images using hyperspectral techniques to help doctors in interpretation of endoscopic images.
