Fiber Pattern Removal and Image Reconstruction Endoscopic Devices and Related Methods

A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for image reconstruction, the operations comprising:

• receiving 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 in the image a plurality of fiber core locations corresponding to the plurality of optical fibers in the optical fiber bundle;
• reconstructing 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 a fiber-pattern removed image in which the artifacts in the acquired image are removed using the missing information;
• and
• performing spectral correction for the fiber-pattern removed image by correcting spectral distortions associated with the endoscopic system.

A system, comprising:

• an endoscopic system;
• a client-side computing device;
• and
• a computer-readable storage device coupled to the client-side computing device and having instructions stored thereon which, are configured to cause the client-side computing device to perform operations for image reconstruction, the operations comprising:
• receiving 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 in the image a plurality of fiber core locations corresponding to the plurality of optical fibers in the optical fiber bundle,
• reconstructing 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 a fiber-pattern removed image in which the artifacts in the acquired image are removed using the missing information, and
• performing spectral correction for the fiber-pattern removed image by correcting spectral distortions associated with the endoscopic system.
