This invention provides a method for generating lace texture images based on an ADM (Adaptive Demographic Model) and dynamic denoising filtering model. This model combines a learnable Gaussian blur layer with a high-pass filtering technique. The Gaussian blur layer adaptively adjusts the blur intensity based on the input image, reducing high-frequency noise in the lace texture image. The high-pass filtering technique enhances key areas such as the outline and edges of the main pattern in the image, thereby highlighting the main texture features. Adding this module to the downsampling layer of the ADM network improves the overly smooth appearance of the lace texture images generated by the original model and enhances the image's texture depth.
