摘要： Approaches to produce verification are addressed which may be suitably employed in conjunction with a low resolution image scanner. Features, such as lines, corners, text, texture, edges and the like are extracted and compared with features for an identified item or evaluated to determine if the features collectively are indicative of a produce item or a non-produce item.

摘要： A method of categorizing defects in a media item. The method comprising the steps of: receiving a binarised image of the media item, where the binarised image comprises a plurality of pixels, each pixel having either a potential defect intensity or a non-defect intensity; and identifying one or more blobs comprising contiguous pixels each having a potential defect intensity. For each identified blob, the method involves comparing a size of the blob with a damage threshold; ignoring the blob if the blob size is smaller than the damage threshold; and for each identified blob having a size exceeding or equaling the damage threshold, categorizing the identified blob.

摘要： A method and apparatus for identifying a media item. The apparatus includes a module for receiving media items and capturing an image of a received media item. The method involves ascertaining external dimensions of the media item from the captured image; creating a monochromatic image based on high contrast boundaries within the captured image; matching the monochromatic image to one of a plurality of templates of media items of approximately the same external dimensions as the media item; and providing details of the matched template, including type and orientation of the media item corresponding to the matched template.

摘要： A voice communication end device provides echo reduction when operating in a full duplex mode using acoustic echo cancellation, which includes periodic audio queue adjustments to account for drift. The end device performs a quality assessment by calculating consistency statistics for the queue adjustments to determine whether acoustic echo cancellation would be ineffective, and if so falls back to a half duplex mode using voice switching.

摘要： The quality and robustness of audio echo cancellation is enhanced by selectively applying glitch recovery processes based on a quality measurement of the relative offset between capture and render audio streams. For example, large and small glitch detection is enabled for low relative offset variance; large glitch detection is enabled in a medium range of relative offset variance; and neither enabled at high variance. Further, a fast glitch recovery process suspends updating the adaptive filter coefficients of the audio echo cancellation while buffers are re-aligned to recover from the glitch, so as to avoid resetting the adaptive filter. When clock drift exists between capture and render audio streams, a multi-step compensation method is applied to improve AEC output quality in case the drifting rate is low; and a resampler is used to compensate the drift in case the drifting rate is high. An anti-clipping process detects clipping of the signals, and also suspends adaptive filter updating during clipping.
摘要翻译：通过基于捕获和渲染音频流之间的相对偏移的质量测量来选择性地应用毛刺恢复过程来增强音频回声消除的质量和鲁棒性。例如，对于低相对偏移方差，启用大的和小的毛刺检测; 在相对偏移方差的中等范围内启用大毛刺检测; 并且在高方差时都不启用。此外，快速毛刺恢复处理暂停更新音频回声消除的自适应滤波器系数，同时缓冲器被重新对准以从毛刺恢复，以避免复位自适应滤波器。当捕获和渲染音频流之间存在时钟漂移时，应用多步补偿方法来提高漂移率低的AEC输出质量; 并且在漂移速率高的情况下使用重采样器来补偿漂移。反剪辑过程检测信号的剪辑，并且还可以在剪辑期间暂停自适应滤波器更新。

摘要： A communications device is presented for providing bi-directional audio communications between a near-end user and a far-end user via a bidirectional communications channel. The communications device includes an adaptive echo canceller receiving a near-end audio signal and a far-end audio signal and providing an echo-canceled near-end audio signal for transmission to the far-end user via the communications channel. The adaptive echo canceller includes a first bank of analysis filters for filtering the near-end audio signal, a second bank of analysis filters for filtering the far-end audio signal, and a bank of synthesis filters for filtering sub-band echo-canceled signals generated within the adaptive echo canceller. The first and second filter banks have a frequency response optimized to reduce echo residual gain.
