This study overcomes the above limitation. At the noise pixel detection step, the algorithm uses an adaptively sized window to help distinguish the noise candidate points as real noise pixels or texture pixels based on the observation that the noise pixels are usually isolated pixels, whose value changes suddenly compared to the surrounding values.
