Abstract: Segments for a video are transmitted in payload units with a supplemental enhancement information (SEI) message within which is embedded display adaptation information that may be employed to control display brightness and thereby reduce power consumption during display of the respective segment. The display adaptation information includes at least a maximum pixel brightness that may be used to scale pixel brightness to maximum and correspondingly reduce backlighting for liquid crystal displays, or to adjust the supply voltage for OLED displays. The display adaptation information may optionally include a minimum pixel brightness, a pixel histogram step size, and an indicator of scaling method.

Abstract translation: 视频的片段以有效载荷单元发送，其中附加增强信息（SEI）消息是嵌入的显示适配信息，其可用于控制显示亮度，从而降低显示各个段期间的功耗。 显示适配信息至少包括可以用于将像素亮度最大化并且相应地减少液晶显示器的背光或者调整OLED显示器的电源电压的最大像素亮度。 显示器适配信息可以可选地包括最小像素亮度，像素直方图步长和缩放方法的指标。

Abstract: To improve precision of visual search processing, SIFT points within a query image are forward matched to features in each of a plurality of repository images and SIFT points within each repository image are backward matched to features within the query image. Forward-only, backward-only and forward-and-backward matches may be weighted differently in determining an image match. Two way matching may be triggered by query image bit rate in excess of a threshold or by a sum of weighted distances between matching points exceeding a threshold. Significant performance gains in eliminating false positive matches are achieved.

Abstract translation: 为了提高视觉搜索处理的精度，查询图像内的SIFT点与多个存储库图像中的每一个中的特征向前匹配，并且每个储存库图像内的SIFT点与查询图像内的特征反向匹配。 在确定图像匹配时，仅向前，向后和向前和向后的匹配可以被不同地加权。 可以通过超过阈值的查询图像比特率或超过阈值的匹配点之间的加权距离之和来触发双向匹配。 实现消除假阳性匹配的显着性能提升。

Abstract: Segments for a video are transmitted in payload units with an extended network abstraction layer unit (NALU) header or supplemental enhancement information (SEI) message within which is embedded display adaptation information that may be employed to control display brightness and thereby reduce power consumption during display of the respective segment. The display adaptation information includes at least a maximum pixel brightness that may be used to scale pixel brightness and correspondingly reduce backlighting for liquid crystal displays, or to adjust the supply voltage for OLED displays. The maximum pixel brightness is set to a level saturating a portion of the pixel histogram without perceptual loss to the viewer, resulting in further reduction of power consumption.

Abstract translation: 视频的片段以有效载荷单元以扩展网络抽象层单元（NALU）头或补充增强信息（SEI）消息进行发送，其中嵌入的显示适配信息可用于控制显示亮度，从而降低显示期间的功耗 的相应段。 显示器适配信息至少包括可用于缩放像素亮度并相应地减小液晶显示器背光的最大像素亮度，或者调整用于OLED显示器的电源电压。 将最大像素亮度设置为饱和像素直方图的一部分而不会对观看者产生感知损失的水平，从而进一步降低功耗。
