An in-place texture synthesis technique for memory constrained multimedia applications

Despite the rapid evolution of multimedia content, from 2D to 3D and to stereo on IMAX display, material and texture remain an indispensable component when rendering realistic and appealing graphics and animations. As the demand for high-definition displays increases, so is the necessity for high-resolution textures. Nevertheless, the available texture images very often have low resolution and are inadequate for high-quality rendering. Texture synthesis from examples offers an effective way not only for the creation of high resolution texture, but also useful in interpolating missing data resulted from unreliable transmission and overly compressed data. We present a new memory-efficient technique that facilitates high-quality texture synthesis. We compare the time performance and memory usage between our approach and the commonly used caching techniques. Experimental results show that our method can perform better, given limited memory resources.
