Detecting image impairments in an interpolated image |
摘要 |
<p>The present invention provides a method and apparatus for detecting image impairments caused by interpolation in an output image interpolated from two or more input images. The method comprises applying a substantially shift invariant transform to the interpolated image and to at least one of the input or adjacent images to derive a transformed image representation for each image. The transformed image representations of the interpolated image and the at least one adjacent image are then compared and differences between the transformed image representations indicative of image impairments in the output image caused by interpolation are determined based on the results of the comparison.</p> |
