Comparison of time complexity in median filtering on multi-core architecture
B. Sharmila, Narasimha Kaulgud · 2017
Median filtering is a nonlinear neighborhood technique which is widely used to remove noise in the image especially salt and pepper noise. Furthermore, median filtering techniques is efficient technique compared to other linear techniques which preserve the edges of the image. However in the median filtering majority of the time will be spent on calculating a median of the each window which results in high computation and time. The purpose of this paper is to design an efficient algorithm for median filtering using python programming and multi-core processor architecture in general purpose operating system which reduces time complexity.
