A super-resolved demosaicing technique for rendering focused plenoptic camera data performs simultaneous super-resolution and demosaicing. One of the great things about the JES interpreter is that it allows you to define procedures that produce great visual effects. Adaptive Homogeneity-Directed demosaicing algorithm by H. Demosaicing using Malvar-He-Cutler algorithm (). Digital Color Images are usually represented by three color values at each pixel. Thus, we came up with the idea of Pixel Shifting — shift the sensor by one-pixel up-down-left-right to catch them all. Algorithms team. By applying the proven NVIDIA CUDA parallel processing technology, we have managed to achieve an extremely high performance of our algorithms on GPU. You won’t even have to pay your internet company for a better internet speed plan!. 1 HDR PhotoStudio 2.
