1. A computer-implemented method for image reconstruction, the method being executed using one or more processors and comprising:
receiving, by the one or more processors, an image acquired by an endoscopic system comprising an optical fiber bundle comprising a plurality of optical fibers, wherein each of the plurality of optical fibers is surrounded by cladding;
determining, by the one or more processors, in the image a plurality of fiber core locations corresponding to the plurality of optical fibers in the optical fiber bundle;
reconstructing, by the one or more processors, missing information from the image using interpolation performed in accordance with the plurality of fiber core locations, wherein the missing information corresponds to artifacts in the acquired image that result from the cladding;
providing, by the one or more processors, a fiber-pattern removed image in which the artifacts in the acquired image are removed using the missing information; and
performing, by the one or more processors, spectral correction for the fiber-pattern removed image by correcting spectral distortions associated with the endoscopic system.
