Another option would be to disable lrf for images smaller than something. I doubt it would have a beneficial impact if any. |

This fixes a crash in LRF at widths or heights of 1 px as a side effect of disabling restoration at sizes where it is not likely to improve quality.

@lu-zero I updated the PR with this solution and added an assertion when initializing the restoration context. |

Found this while fuzzing and took the easy way out. An alternative or complementary solution would be to assert that the frame size is valid and display a proper error message if it is not (I could not find the minimum frame size requirements in the spec, but I seem to recall they exist).
