mathematically, applying a gaussian blur to an image is the same as convolving the image with a gaussian function.
数学上讲,对图像做高斯模糊等同于将图像与高斯函数卷积。
denoise: noise reduction plugin using a modified gaussian blur algorithm.
denoise:使用高斯模糊算法的降噪插件。
after, add some gaussian blur (filter > blur > gaussian blur). i used just 1 pixel.
之后,增加一些高斯模糊。
a simple gaussian blur tool can create the same effect.
使用高斯模糊即可创造类似效果。
fill the selection with white, then give the layer a 170% gaussian blur .
用白色填充选择,然后给层了170%高斯模糊 。
soften the shadow by adding gaussian blur filter.
柔化阴影,加入高斯模糊滤镜。
the only filter i used here is gaussian blur which i used to create the shade applied to the black oval shape.
唯一的过滤器我用在这里是高斯模糊,我用来创建应用到黑色椭圆形状的阴影。
a novel image texture feature descriptor is proposed which is insensitive to gaussian blur and gaussian noise.
提出了一种对高斯模糊和高斯噪声鲁棒的图像纹理特征描述算子。
next, duplicate the layer just created and move the new layer to the top. this duplicated layer will be blurred again using the gaussian blur filter. however, use a higher radius such as 35 this time.
once this was done i applied a gaussian blur with a radius of 250px twice and set the layer up as overlay at %.
一旦这样做,我申请一个半径为250像素的高斯模糊两次,并设置在%覆盖层。
now use the arrows on your keyboard to move the shadow to the bottom left of the rectangle, then give it a gaussian blur with a radius of 1.5 pixels and bring down the opacity of the layer to 10%.
