Abstract
Embodiments of the present invention provide for thresholding data elements (such as coefficients). According to one embodiment, a number of functions (including feature detector functions) can be applied to a data element to generate responses. Additionally, noise profiles can be consulted to determine an expected result for each function if the data element represents noise. An output value (e.g., after thresholding) for the data element can be generated based on the actual responses of the functions and the expected responses.
