Abstract
A method and apparatus for adjusting the effect of applying a kernel to a signal is provided. The adjustment may be based on the magnitude of an effect that a kernel matrix is intended to have on the signal matrix. The adjustments can be based on factors including, but not limited to, a signal-to-noise ratio of the signal data, properties of a device (e.g., lens) used to capture the signal data, or a metric that is derived based on an analysis of the signal data. Processing image data in accordance with an embodiment of the present invention is aimed at regaining lost contrast that may be due to properties of optics that are used to capture the image data.
