Zusammenfassung: | The invention relates to a digital watermark signature verification method, device and equipment based on fused news materials. The method comprises the following steps: establishing a news material video database, performing frame-by-frame extraction on a news material video, converting a video frame into a YUV image, performing feature extraction on the video frame, and constructing a feature region; preprocessing a Y-channel image in the feature region and then converting the Y-channel image from a spatial domain to a frequency domain; dividing the watermark image into two parts, embedding one part into a Y channel frequency domain image, inputting the embedded part into an adversarial network, and converting an obtained result from a frequency domain to a spatial domain to obtain a first watermark-containing spatial domain image; embedding the other part of watermark into the Y channel image except the feature region, and then inputting the Y channel image into the adversarial network to obtain a second w |
