this technical poster studies the advantages and disadvantages of Fractal image Compression (FIC) compared to Wavelet Transform Compression (WTC). Our results indicate that there is an advantage in FIC for high compre...

Maximum entropy (MENT) is a well-known image reconstruction algorithm. If only a small amount of acquisition data is available, this algorithm converges to a noisy and blurry image. We propose an improvement to this a...

Game engines typically use cube maps or screen space local reflections for simulating reflections effects at the real-time renderer pipeline. While these techniques work in many situations, they cannot deal well with reflections of reflections, reflections from covered spaces, reflections from elements outside the screen space or reflections from elements that change its shape or position in real-time. In this paper, we present a method capable of creating true real-time ray-traced reflections by using a heuristic based method and a hybrid renderer. Our solution maintain real-time frame rates by selecting, for each frame, the best reflexive surfaces to ray trace, based on the users point of view.
Presents several extensions of the basic control point assessment (CPA) algorithm. First, we compare CPA to standard corner detection algorithms and then turn to the question of selecting control points with adequate ...
