Highly Parallel Implementation of Retina Image Enhancement on Gpu to Enable Faster Execution
نویسندگان
چکیده
The analysis of retinal images is becoming a vital medical tool to predict retinopathy and other retinal impairments. The algorithms implemented on CPU are able to process retinal images. However, the algorithms running on CPU are executed sequentially. This is due to the hardware limitation of CPU. GPU are having inherent hardware architecture to enable parallel implementation of image processing task and thus bringing an upshot in fleetness. This paper discusses about retinal image enhancement by using algorithm running on GPU. The hardware used is NVIDIA GeForce GT 720M.

متن کاملParallel Implementation of Color Based Image Retrieval Using CUDA on the GPU
Most image processing algorithms are inherently parallel, so multithreading processors are suitable in such applications. In huge image databases, image processing takes very long time for run on a single core processor because of single thread execution of algorithms. Graphical Processors Units (GPU) is more common in most image processing applications due to multithread execution of algorithm...
