With the advent of the digital age, many precious photos were scanned and saved on the computer. However, these photos always have some defects due to some natural or unnatural factors when preserving. Besides that, sometimes we need to selectively remove some parts of the picture which are not interested in. Under this condition, the

With the continuing development of computer science and multimedia techniques, simple image texture can’t meet the needs of all applications. For instance in video production, virtual simulation, animation production and the game engine, video textures are widely used. A video texture provides a continuous infinitely varying stream of images. While the individual frames of a

Texture synthesis and transfer are research hotspot of computer graphics and computer vision. They are widely used in virtual reality, computer vision and so on. Texture synthesis technology which proposed to solve seams has more applications. As seam aliasing and discontinuity exist in randomly puzzle, and image processing technology is developed quickly, research work on

Image completion or inpainting aims at repairing damaged paintings or removingobjects in images. Traditional approaches are PDE-based diffusing or restoring the targetusing texture synthesis, which must sample in the original image. Problems remainedwhere users want to repair the target object in a picture. Object completion has twochallenges. Firstly, the target object might have its specific

The realistic modeling and rendering of trees lies not only in the form of trees, but also in the simulation of the tree surface detail. The high realistic simulation of the bark detail texture plays an important role on improving the realism of trees. Since most tree modeling, in particular, the model obtained by computing

Virtual Surgery is the application of Virtual Reality technology in the field of modern medicine. The development and application of the Virtual Surgery system can not only provide the endoscopic surgery training platform for doctors, but also support real surgery. Its emergence promotes the popularity and application of endoscopic surgery greatly. Therefore, the Virtual Surgery

Image inpainting is an ancient art. In renaissance of Europe, people have repaired the cracks of the work of fine art. They can resume the damaged portions of a work of fine art and keep it whole by this way. As the advent and development of computer technology, digital image inpainting was introduced into the
