    Abstract: Watermark data is converted to watermark coefficients, which may be embedded in an image by converting the image to a frequency domain, embedding the watermark in image coefficients corresponding to medium-frequency components, and converting the modified coefficients to the spatial domain. The watermark data is extracted from the modified image by converting the modified image to a frequency domain, extracting the watermark coefficients from the image coefficients, and determining the watermark data from the watermark coefficients. The watermark data may be truncated image data bits such as truncated least significant data bits. After extraction from the watermark, the truncated image data bits may be combined with data bits representing the original image to increase the bit depth of the image. Watermark data may include audio data portions corresponding to a video frame, reference frames temporally proximate to a video frame, high-frequency content, sensor calibration information, or other image data.

    Abstract translation: 水印数据被转换为水印系数，其可以通过将图像转换为频域而嵌入到图像中，将水印嵌入对应于中频分量的图像系数中，并将修改的系数转换为空间域。 通过将修正图像转换为频域，从图像系数中提取水印系数，并根据水印系数确定水印数据，从修改图像中提取水印数据。 水印数据可以是截断的图像数据位，例如截断的最低有效数据位。 在从水印提取之后，截断的图像数据位可以与表示原始图像的数据位组合，以增加图像的位深度。 水印数据可以包括对应于视频帧的音频数据部分，时间上靠近视频帧的参考帧，高频内容，传感器校准信息或其他图像数据。

    Abstract: Video and corresponding metadata is accessed. Events of interest within the video are identified based on the corresponding metadata, and best scenes are identified based on the identified events of interest. In one example, best scenes are identified based on the motion values associated with frames or portions of a frame of a video. Motion values are determined for each frame and portions of the video including frames with the most motion are identified as best scenes. Best scenes may also be identified based on the motion profile of a video. The motion profile of a video is a measure of global or local motion within frames throughout the video. For example, best scenes are identified from portion of the video including steady global motion. A video summary can be generated including one or more of the identified best scenes.
