Abstract

A method for recognizing whether an image comprises a watermark comprises: obtaining a sample specification image set, and adjusting sample images in the sample specification image set to a preset size (S102); calculating average values of pixel attribute values of the sample images in the sample specification image set at pixel positions of the preset size (S104); normalizing the average values of the pixel attribute values at the pixel positions of the preset size, so as to obtain watermark probability values at the pixel positions of the preset size (S106); and obtaining a target image the size of which has been adjusted to the preset size, and calculating the sum of products between pixel attribute values of the target image at the pixel positions of the preset size and the corresponding watermark probability values, and determining whether the target image comprises a watermark according to the sum of the products (S108). The method has a high recognition accuracy rate. Fig. 2
