We present a GPU-based implementation of the saliency model proposed by Achanta et al. [1] to perform real-time and detailed saliency map generation. We map all the components of the algorithm to GPU-based kernels and data structures. the parallel version of the algorithm is able to accurately simulate the desired results in a very low time. We describe the streaming pipeline and address many issues in terms of obtaining high throughput on multi-core GPUs. We highlight the parallel performance of the algorithm on three different generations of GPUs. On a high-end NVIDIA Tesla K20m, we observe up to 600x order of magnitude performance improvement as compared to a singlethreaded CPU-based algorithm, and about 300x order of magnitude improvement over a CPU-based OpenCV implementation.

Simulation and rendering of material weathering is of great interest in computergraphics as it facilitates modeling of realistic objects in virtual scenes. We present a physiochemically based methodology to model pitting corrosion. Our simulation has two components. the first models pit nucleation on the surface of the object. It is implemented as a stochastic process, exponentially deteriorating with time. the second component models pit growth using another stochastic process inuenced by pit characteristics (geometry, neighborhood and exposure). We validate our model with measurements published in the corrosion literature and then demonstrate its effectiveness in generating realistic images. Our corrosion model leads to shape degradation. Color degradation is less tractable. Hence we instead learn that directly from acquired images of corroded models. We present an efficient rendering algorithm that generates color, normal and depth textures to display the corrosion of any object of interest. this is an important step in linking the appearance to structural damage.
