    • 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.
    • 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。

    • A method and a system for transmitting data are provided. In a source apparatus, original data is divided into a plurality of source segments, a similarity calculation is performed for each of the source segments to obtain a similarity set, and the similarity set is transmitted to a target apparatus. In the target apparatus, whether a target segment corresponding to the source segment exists in the target apparatus is determined according to the similarity set to obtain a comparison result, and the comparison result is transmitted to the source apparatus. In the source apparatus, after the original data is dehydrated according to the comparison result to obtain dehydration data, the dehydration data is transmitted to the target apparatus. In the target apparatus, the dehydration data is rehydrated to the original data.
    • 提供了一种用于发送数据的方法和系统。 在源装置中,将原始数据分割为多个源片段,对每个源片段进行相似度计算,以获得相似度集合,并将相似度集合发送到目标装置。 在目标装置中,根据相似性确定目标装置中是否存在与源段对应的目标段,以获得比较结果,并将比较结果发送到源装置。 在源装置中,在根据比较结果对原始数据进行脱水以获得脱水数据之后,将脱水数据发送到目标装置。 在目标装置中,将脱水数据再水化为原始数据。
