    • Encoding and decoding methods that perform quantization using adaptive reconstruction levels are presented. The reconstruction levels for a given partitioning of the data space may be selected based upon the distribution of data points within each sub-part defined by the partitioning. In some cases, the adaptive reconstruction levels may be based upon an average of the data points within each sub-part. In some cases, the adaptive reconstruction levels may be selected using a rate-distortion analysis including the quantization distortion associated with the levels versus the data points and the rate associated with transmitting the encoded adaptive reconstruction levels. The methods relate to data compression in a range of applications including audio, images and video.
    • 提出了使用自适应重建级别执行量化的编码和解码方法。 可以基于由分区定义的每个子部分内的数据点的分布来选择数据空间的给定划分的重建级别。 在一些情况下,自适应重建级别可以基于每个子部分内的数据点的平均值。 在一些情况下,可以使用包括与电平相对于数据点相关联的量化失真的速率失真分析以及与发送编码的自适应重建级别相关联的速率来选择自适应重建级别。 该方法涉及包括音频,图像和视频在内的一系列应用中的数据压缩。

    • Down-sampling of an image may be performed in the DCT domain. Transform matrices are obtained for down-sampling a DCT image of size M×N to a down-sampled DCT image of size I×J. The transform matrices may be used to down-sample the DCT image directly in the DCT domain. A spatial domain down-sampling method is selected and applied to the DCT image to produce a down-sampled DCT reference image. The transform matrices are selected by solving an optimization problem, leading to transform matrices which achieve a desired trade-off between the visual quality of images obtained using the transform matrices and the computational complexity associated with using the transform matrices. The visual quality is a measure of the difference between the down-sampled DCT image obtained using the transform matrices and the visual quality of the DCT reference image obtained using a spatial domain down-sampling method.
    • 可以在DCT域中执行图像的下采样。 获得变换矩阵,以将尺寸为M×N的DCT图像下降为尺寸为I×J的下采样DCT图像。 变换矩阵可以用于在DCT域中直接对DCT图像进行下采样。 选择空间域下采样方法并将其应用于DCT图像以产生下采样DCT参考图像。 通过求解优化问题来选择变换矩阵,导致变换矩阵,其在使用变换矩阵获得的图像的视觉质量和与使用变换矩阵相关联的计算复杂度之间实现期望的权衡。 视觉质量是使用变换矩阵获得的下采样DCT图像与使用空间域下采样方法获得的DCT参考图像的视觉质量之间的差的度量。

    • A mounting apparatus includes a bracket receiving a disk drive, a locking member and a first resilient member. The bracket includes two first sidewalls and two second sidewalls. Each first sidewall is connected to the two second sidewalls and defines a number of through holes. The locking member includes two frames rotatably secured to the two first sidewalls. Each frame includes a number of pins. The first resilient member is connected to the two frames. Each frame is rotatable between a first position, where the pins are inserted in the bracket via the through holes, and a second position, where the pins are located out of the bracket. The first resilient member is deformed when each frame is rotated from the first position to the second position, and each frame is rotated from the second position to the first position when the first resilient member returns.
    • 安装装置包括容纳盘驱动器的托架,锁定构件和第一弹性构件。 托架包括两个第一侧壁和两个第二侧壁。 每个第一侧壁连接到两个第二侧壁并且限定多个通孔。 锁定构件包括可旋转地固定到两个第一侧壁的两个框架。 每个帧包括多个引脚。 第一弹性构件连接到两个框架。 每个框架可以在第一位置和第二位置之间转动,第一位置和第二位置之间的销被插入支架中,第二位置位于支架的外部。 当每个框架从第一位置旋转到第二位置时,第一弹性构件变形,并且当第一弹性构件返回时,每个框架从第二位置旋转到第一位置。
