摘要： A system and method for defringing chromatic aberrations that occur in imaging devices such as scanners. The system comprises shift filters to shift lines in the various color planes together. In addition in each color plane, a spread filter is used to compensate for the unequal point spread functions of each color. Furthermore, the results can be enhanced by filtering in the luminance-chrominance space.
摘要翻译：一种用于降低诸如扫描仪的成像装置中出现的色差的系统和方法。该系统包括移位滤波器以将各种颜色平面中的线移动到一起。另外在每个颜色平面中，扩展滤波器用于补偿每种颜色的不等点扩散函数。此外，可以通过在亮度 - 色度空间中进行滤波来增强结果。

摘要： In many audio playback systems, frequencies below a given cut off frequency are suppressed either due to speaker constraints or safety constraints. For example, some speakers are only capable of generating signals above a certain frequency. Prolonged low frequency sound can cause damage to speakers or other components. An audio driver can be equipped with a phantom bass module which by doubling, tripling and/or quadrupling frequencies below a cutoff frequency can simulate the bass experience. The doubling, tripling and quadrupling methods disclosed provide a low complexity formulation of a frequency doubling, tripling and quadrupling. In addition, the frequency doubling, tripling and quadrupling formulations are easily adapted to multi-rate processing, where computational savings can be very high.
摘要翻译：在许多音频播放系统中，由于扬声器约束或安全限制，抑制给定截止频率以下的频率。例如，一些扬声器只能产生高于特定频率的信号。延长的低频声音可能会损坏扬声器或其他部件。音频驱动器可以配备幻影低音模块，通过将截止频率以下的频率加倍，三倍和/或四倍，可以模拟低音体验。所公开的加倍，三倍和四倍的方法提供了倍频，三倍和四倍的低复杂度公式。此外，倍频，三倍和四倍的配方可以很容易地适用于多速率处理，其中计算节省可能非常高。
