com.aspose.imaging.Image image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用矩形大小为5的中值滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.MedianFilterOptions(5));
    rasterImage.save(dir + "sample.MedianFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用核大小为5的双边平滑滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.BilateralSmoothingFilterOptions(5));
    rasterImage.save(dir + "sample.BilateralSmoothingFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用半径为5、sigma值为4.0的高斯模糊滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.GaussianBlurFilterOptions(5, 4.0));
    rasterImage.save(dir + "sample.GaussianBlurFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {

    // 对整幅图像应用半径为5、平滑值为4.0的Gauss-Wiener滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.GaussWienerFilterOptions(5, 4.0));
    rasterImage.save(dir + "sample.GaussWienerFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用长度为5、平滑值为4.0、角度为90.0度的运动Wiener滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.MotionWienerFilterOptions(10, 1.0, 90.0));
    rasterImage.save(dir + "sample.MotionWienerFilter.png");
} finally {
    image.dispose();
}

image = com.aspose.imaging.Image.load(dir + "sample.png");
try {
    com.aspose.imaging.RasterImage rasterImage = (com.aspose.imaging.RasterImage) image;

    // 对整幅图像应用核大小为5、sigma值为4.0的锐化滤波器。
    rasterImage.filter(rasterImage.getBounds(), new com.aspose.imaging.imagefilters.filteroptions.SharpenFilterOptions(5, 4.0));
    rasterImage.save(dir + "sample.SharpenFilter.png");
} finally {
    image.dispose();
}
