    • 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.
    • 根据与另一颜色通道中的相应像素的位移对应的颜色通道中的像素来降低色差的系统和方法。 特别地,系统为图像的第一颜色通道中的第一像素块计算诸如强度的特征。 为图像的第二颜色通道中的第二像素块计算特征。 通过比较第一块的特征和第二块的特征,估计在第一颜色通道和第二颜色通道之间的位移。 基于估计的位移,第一颜色通道的至少一部分与第二颜色通道的至少一部分对准。

    • At least one implementation reduces chromatic aberration by aligning pixel in a color channel according to displacement from corresponding pixels in another color channel. In one particular implementation, a feature is calculated 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.
    • 至少一个实现通过根据在另一个颜色通道中的相应像素的位移来调整颜色通道中的像素来减少色差。 在一个特定实现中,针对图像的第一颜色通道中的第一像素块计算特征。 为图像的第二颜色通道中的第二像素块计算特征。 通过比较第一块的特征和第二块的特征,估计在第一颜色通道和第二颜色通道之间的位移。 基于所估计的位移,第一颜色通道的至少一部分与第二颜色通道的至少一部分对准。

    • Embodiments of packet loss concealment in a hearing assistance device are generally described herein. A method for packet loss concealment can include receiving, at a first hearing assistance device, a first encoded packet stream from a second hearing assistance device and a signal frame. The method can include encoding, at the first hearing assistance device, the signal frame and determining, at the first hearing assistance device, that a second encoded packet stream was not received from the second hearing assistance device within a predetermined time. In response to determining that the second encoded packet stream was not received, the method can include decoding, at the first hearing assistance device, the encoded signal frame, and outputting the signal frame and the decoded signal frame.
    • 这里一般地描述助听装置中的分组丢失隐藏的实施例。 一种用于分组丢失隐藏的方法可以包括在第一听力辅助装置处接收来自第二助听装置的第一编码分组流和信号帧。 该方法可以包括在第一听力辅助装置处编码信号帧,并且在第一听力辅助装置处确定在预定时间内没有从第二听力辅助装置接收到第二编码分组流。 响应于确定未接收到第二编码分组流,该方法可以包括在第一听力辅助设备处对编码的信号帧进行解码,以及输出信号帧和解码的信号帧。

    • 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。
