It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention to further modify MANDELKERN to have applying the recursive sharpness enhancement to the received input medical image comprises applying Fast Recursive Adaptive Unsharp Masking of COTE reference. The Suggestion/motivation for doing so would have been to provide an unsharp mask which results in improving the enhancement of textures and edges while also reducing noise in the output image as suggested by paragraph [0917] of COTE. Further, one skilled in the art could have combined the elements as described above by known method with no change in their respective functions, and the combination would have yielded nothing more than predictable results. Therefore, it would have been obvious to combine COTE with modified MANDELKERN to obtain the invention as specified in claim 19. As per claim 20, MANDELKERN in view of KIELY in view of ZHOU discloses the non-transitory computer-readable storage medium of claim 18. Modified MANDELKERN fails to disclose wherein applying the recursive sharpness enhancement to the received input medical image comprises applying Fast Recursive Adaptive Unsharp Masking (FRA-UM) using the sliding window to obtain the sharpened image by 1-dimensional (ID) recursive scheme based on double scanning of the input medical image. COTE discloses wherein applying the recursive sharpness enhancement to the received input medical image comprises applying Fast Recursive Adaptive Unsharp Masking (FRA-UM) using the sliding window to obtain the sharpened image by 1-dimensional (ID) recursive scheme based on double scanning of the input medical image (the computing system is adapted to apply an unsharp masking step and this step would be applied iteratively (recursively) if used in the steps of MANDELKERN and would result in x-ray image enhancement by sharpening the images edges, and improving the enhancement of textures and edges while also reducing noise in the output image and utilizes a 1-d motion table lookup table which comprises 237 entries; paragraphs [0591-0594], [0898-0901], [0917]). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention to further modify MANDELKERN to have applying the recursive sharpness enhancement to the received input medical image comprises applying Fast Recursive Adaptive Unsharp Masking of COTE reference. The Suggestion/motivation for doing so would have been to provide an unsharp mask which results in improving the enhancement of textures and edges while also reducing noise in the output image as suggested by paragraph [0917] of COTE. Further, one skilled in the art could have combined the elements as described above by known method with no change in their respective functions, and the combination would have yielded nothing more than predictable results. Therefore, it would have been obvious to combine COTE with modified MANDELKERN to obtain the invention as specified in claim 20.
