| 摘 要： | 提出一种新的利用人眼视觉特性去噪方法，该方法充分考虑利用人眼视觉特性确定噪声点，根据窗口内噪声点个数自适应选择合适的滤波窗口大小，采用B样条函数和中值滤波方法对噪声点进行逐点滤除。论文最后给出模拟实验和分析，结果表明该方法是有效的，既能有效地去除图像噪声点，又能较好地保持图像细节部分，为去除图像中的噪声提供了一种新的方法。

| Abstract: | This paper proposed a new remove noises methed based on human vision system,In our algorithm we fully considers the characteristics of humanity visual characteristic and detected the noise pixel according,the filter window size was adaptively adjusted according to the window size,finally used the b-spline function and median filter to estimate noise pixels.The paper finally produced the experiments and the result analysis,This algorithm can effectively remove noises and also retain image details very well.I... |
