Application with sequential algorithm can no longer rely on technology scaling to improve performance. Image processing applications exhibits high degree of parallelism and are excellent source for multicore platform. Major challenge of parallel processing is not only aim to high performance but is to give solution is less time and better utilization of resources. This paper focus on calculating the various parameters such as fork time, join time, serial time, parallel time, overheads. The results show that the leveraging of multicore platforms can speed up considerably the processing of images through the use of parallel computing tools in matlab.
