A Graphcut Approach for Texture Synthesis
نویسنده
چکیده
Texture synthesis is generating a newer form of output from a smaller example. It is widely recognized to be important for many applications in computer graphics, vision, and image processing. Graphcut is the key technology of texture synthesis. It decides which parts of the input image to patched into the output texture. After finding a good patch offset between two inputs, we computer the best patch seam (the seam yielding the highest possible MRF likelihood among all possible seams for that offset). In this project, two overlapped images are copied to the output, cut by max-flow/min-cut algorithm and then stitched together along optimal seams to generate a new output.

Theoretical Analysis of Graphcut Textures
Since the paper was published in SIGGRAPH 2003, the graphcut textures has become a popular and important technique for both static and dynamic image texture synthesis. However, the discussion on the theoretic side of the graphcut textures appears lacking with little information provided in the original paper to convince the reader the correctness of the approach. This paper addresses the import...
متن کاملGraphcut Texture Synthesis for Single-Image Superresolution
Texture synthesis has proven successful at imitating a wide variety of textures. Adding additional constraints (in the form of a low-resolution version of the texture to be synthesized) makes it possible to use texture synthesis methods for texture superresolution. The Single-image Superresolution Problem The problem we are trying to solve is the following: Given: a low-resolution image and hig...
متن کاملA Novel Texture Synthesis Based Algorithm for Object Removal in Photographs
Natural images and photographs sometimes may contain stains or undesired objects covering significant portions of the images. Inpainting is a method to fill in such portions using the information from the remaining area of the image. In this paper, we propose a novel photograph editing framework that utilizes texture synthesis techniques. Major contributions of our algorithm are: 1) a constrain...
متن کاملA Two Level Montage Approach to Sound Texture Synthesis with Treatment of Unique Events
In this paper a novel algorithm for sound texture synthesis is presented. The goal of this algorithm is to produce new examples of a given sampled texture, the synthesized textures being of any desired duration. The algorithm is based on a montage approach to synthesis in that the synthesized texture is made up of pieces of the original sample concatenated together in a new sequence. This monta...
متن کاملFast three-dimensional Texture Synthesis
Three-dimensional (3D) textures are popular for texturing solid objects. They usually achieve superior results over conventional two-dimensional (2D) texture mapping techniques. However, whereas 2D textures can be obtained using for example a photograph, capturing or generating solid textures is not straightforward. Procedural techniques can replicate some types of materials, but are usually di...
