| Description: | Image processing and computer vision algorithms allow computers to make sense of pictures and video seen through cameras. These have applications in a large variety of real time" applications like surveillance, intelligence gathering, robotics, automobile driving, aviation, etc., where the picture from the video needs to be processed by a computer as soon as it is taken. However these algorithms are time intensive because of its compute bound nature. In this literature, a single image super resolution algorithm based on Neighborhood Dependent Component Feature Learning (NDCFL) is accelerated by multiple GPUs and multiple CPU cores, using NVIDIA's Computer Unified Device Architecture (CUDA), OpenCV and POSIX threads. Given a low resolution input, this method uses image features to adaptively learn the regression kernel based on local covariance to estimate the high resolution image. The accelerated implementation performs at speed 51 times faster than that of original implementation for 590X580 frame, and achieves processing rate close to real-time." |
