Mathews, V. John; Nilsson, Michael | Adaptive gain processing to improve feedback cancellation in digital hearing aids | Adaptive filters are commonly used to cancel acoustic feedback in hearing aids. The sound quality of hearing aids deteriorates as the hearing aid gain is increased. This paper presents a method to alter the gain function in digital hearing aids to provide additional amplification and better output ... | 2008 | |

Mathews, V. John | Adaptive gain processing with offending frequency suppression for digital hearing aids | Digital hearing aids identify acoustic feedback signals and cancel them continuously in a closed loop with an adaptive filter. This scheme facilitates larger hearing aid gain and improves the output sound quality of hearing aids. However, the output sound quality deteriorates as the hearing aid gai... | 2012 | |

Cohen, Elaine | Adaptive isocurves based rendering for freeform surfaces | Freeform surface rendering is traditionally performed by approximating the surface with polygons and then rendering the polygons. This approach is extremely common because of the complexity in accurately rendering the surfaces directly. Recently, several papers presented methods to render surfaces ... | Freeform surface rendering; Isocurves | 1992 |
