Mid-spatial frequency digital boost filter |
摘要 |
A finite impulse response digital filter is designed for boosting mid-spatial frequencies as opposed to the frequencies near the sensor resolution limit. The digital filter's boost is centered on frequencies at about half the Nyquist frequency. To prevent over-boosting or enhancement of noise, the detail signal can be run through a coring filter to remove any low amplitude detail signal that resulted from noise.
