    • Method and apparatus for microphone matching for wearable directional hearing assistance devices are provided. An embodiment includes a method for matching at least a first microphone to a second microphone, using a user's voice from the user's mouth. The user's voice is processed as received by at least one microphone to determine a frequency profile associated with voice of the user. Intervals are detected where the user is speaking using the frequency profile. Variations in microphone reception between the first microphone and the second microphone are adaptively canceled during the intervals and when the first microphone and second microphone are in relatively constant spatial position with respect to the user's mouth.
    • 提供了一种用于穿戴式定向听力辅助装置的麦克风匹配的方法和装置。 实施例包括使用来自用户嘴部的用户声音来将至少第一麦克风与第二麦克风相匹配的方法。 处理用户的话音由至少一个麦克风接收以确定与用户的语音相关联的频率分布。 使用频率分布检测用户正在说话的间隔。 在第一麦克风和第二麦克风之间的麦克风接收的变化在间隔期间自适应地消除,并且当第一麦克风和第二麦克风相对于用户的嘴处于相对恒定的空间位置时。

    • A system and method for reducing chromatic aberration by aligning pixel in a color channel according to displacement from corresponding pixels in another color channel. In particular, the system calculates a feature, such as intensity, for a first block of pixels in a first color channel of an image. The feature is calculated for a second block of pixels in a second color channel of the image. Displacement is estimated between the first color channel and the second color channel by comparing the feature for the first block and the feature for the second block. At least a portion of the first color channel is aligned with at least a portion of the second color channel based on the estimated displacement.
