This paper proposes a new filtering approach for removing pulse noise in color images. The proposed approach uses either a scalar median filter or a vector median filter according to simple local texture analysis: when the local area is not heavily textured, a scalar filter is used; otherwise a vector filter is used. Since most natural images have a lowpass property, the proposed approach operates on the scalar mode most of the time. Experiments show that the proposed method provides comparable...

This paper proposes a new filtering approach for removing pulse noise in color images. The proposed approach uses either a scalar median filter or a vector median filter according to simple local texture analysis: when the local area is not heavily textured, a scalar filter is used; otherwise a vector filter is used. Since most natural images have a lowpass property, the proposed approach operates on the scalar mode most of the time. Experiments show that the proposed method provides comparable performance with much less computation requirement than a standard vector median filter.

提出一种新的消除彩色图像中脉冲噪声的滤波法.该滤波法依据简单的局部纹理分析而自动选择使用标量中值滤波或者使用矢量中值滤波:当局部区域不存在明显的纹理时,使用标量滤波,否则使用矢量滤波.由于大多数自然图像都有低通特性,因而该滤波器大多数时间运作于标量模式.实验表明,文中提出的方法其计算量比标准的矢量中值滤波器少得多,但性能却同样优良.

This praper proposes a new filtering approach for removing impulsie in color images. The filtre, according tothe decisterion, is given in the ofllowing: if a pixel valie is the extremum(max.or min.)of its neighborhood, it is a noise pixel;else, it is a signal pixel; then noise pixels are replaced with the median value of their neighborhood in the input image. Next,the proposed approach automtically chooses to use either a extrmum scalar median filter or a vector median filter according tosimple local texture...

构建了一种新的消除彩色图象中脉冲噪声的滤波法。该滤波首先根据极值点(最大或最小)的判别标准将全部像素分为两类(信号S与噪声N),再根据空间相关性将噪声点用该点邻域的中值取代,然后进行简单的局部纹理分析而自动选择使用标量中值滤波或者使用矢量中值滤波。实验表明,文中提出的方法计算量少,性能优良,图象信噪比高。

A dim targets detection method based on local texture analysis is proposed on the basis of Multi-Resolution Analysis (MRA). The detection of dim targets is carried out by using local MRA character vector difference of target and background, while the traditional methods always use the gray value difference of target and background of infrared image to realize dim target detection. So this method can reflect the difference between targets and background better and high-efficiency detection...

A dim targets detection method based on local texture analysis is proposed on the basis of Multi-Resolution Analysis (MRA). The detection of dim targets is carried out by using local MRA character vector difference of target and background, while the traditional methods always use the gray value difference of target and background of infrared image to realize dim target detection. So this method can reflect the difference between targets and background better and high-efficiency detection in the strong clutter background can be performed. The simulation experiments for practical measured data show that the method can effectively detect dim targets with 1-3 pixels. When Mallat algorithm and à trous algorithm is applied in wavelet decomposition phase, respectively, single-frame detection can be completed by this method in 0.65s. This represents it with good timeliness.

在多分辨率分析的基础上,提出了一种基于局部纹理分析的小目标检测新方法。利用目标与背景的局部纹理特征差异,在局部距离像上完成小目标的检测;而传统的检测方法利用目标点亮度值与背景亮度值不同进行目标与背景的分离,因此本方法更能体现目标与背景的差异,在强杂波背景中实现高效的检测。对实测数据的仿真实验表明,该方法能有效地检测占极少(1-3 个)像素的小目标;同时,在小波分解阶段分别采用 Mallat 算法和 à trous 算法时,该方法都能在 0.65秒内完成单帧检测,具有良好的实时性能。
