Fiber Pattern Removal and Image Reconstruction Endoscopic Devices and Related Methods

Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for image reconstruction. Actions include receiving an image acquired by an endoscopic system including an optical fiber bundle with multiple optical fibers, each optical fiber being surrounded by cladding, determining in the image fiber core locations corresponding to the optical fibers, reconstructing missing information from the image using interpolation performed in accordance with the fiber core locations, the missing information corresponding to artifacts in the acquired image that result from the cladding, and providing a fiber-pattern removed image, in which the artifacts in the acquired image are removed using the missing information.
