Embodiment Construction

[0015] A texture synthesis method based on controllable pyramid decomposition, involving texture, its special features are:

[0016] First, the target image is read in the matlab software, and an initial image with random and uniform distribution of gray levels is generated. The size of the initial image is determined by the size of the final desired generated texture.

[0017] Next, the initial image is histogram-matched with the target image. Before matching, it is necessary to perform histogram gray equalization processing on the initial image and the target image, and then use the projection rule (CML) to map the histogram of the initial image to the histogram of the target image to complete the matching of the histogram.

[0018] Afterwards, the target image and the random image were decomposed into a 4-layer pyramid, and a total of 18 sub-bands were obtained, including 1 high-frequency sub-band, 1 low-frequency sub-band and 4 layers of band-pass sub-bands in 4 direction...

Abstract

The invention relates to a texture synthesis method based on controllable pyramid decomposition. The method is characterized in that: reading an object image in matlab software, and generating an initial image with random and uniform distribution of gray scale; carrying out histogram coupling on the initial image and an object image; carrying out pyramid decomposition on the object image and a random image respectively, carrying out the histogram coupling on each corresponding sub-band which is decomposed, followed by storing in a pyramid data structure after coupling, and carrying out inverse transformation reconstruction to obtain a new image; and finally carrying out continuous cycle operation to obtain an image whose texture direction is similar to that of the object image. By employing the method, a synthetic image has a clear texture, and an effect is good. Simultaneously, operation is simple, speed is fast, and the method has wide application prospect in aspects of image editing, data compression, rapid transmission of network data, generation of a large scale scene, photorealistic rendering and non-photorealistic rendering and the like.
