Gaussian blur

A type of image filter commonly used to blur an object. It may be used to blur the entire image or to produce a drop shadow effect. See image filter.

A Drop Shadow
The Gaussian Blur filter is widely used to create a drop shadow effect around text. Using an image editor, a duplicate of the text is made, changed to black and then passed through the filter. The blurred result is aligned under the original text to create the effect.

In contrast, for the decreasing-type distortions such as white noise and Gaussian blur, the PLCC and SROCC values are negative in SSP but positive in DMOS and NODS, since the distortion parameter increasing causes the image quality to be worse.
So, we've got a good Gaussian blur implementation - but our "getting-hit" in-game effect requires a large blur kernel and our target hardware is a high res mobile device.

0, is the first-ever incorporation of real-time, multi-stream, 10-bit 50-pixel Gaussian Blur capability.
I then apply a Gaussian Blur filter set to a radius of 25, which eradicates small features.
And XBLUR, an 844/X add-on that for the first time makes possible real-time Gaussian Blur effects, provides TXCN with additional capabilities for adding cinematic-style camera defocus effects and other creative treatments with real-time control.
With the layer mask selected, I apply a Gaussian Blur filter to the mask, varying the radius of the blur until optimal blending of the image layers is achieved.
Delaplaine is leveraging the speed, quality and power of 844/X, especially revolutionary new 844/X enhancements like XBLUR - the industry's first real-time 10-bit 50-pixel Gaussian Blur capability, to expand and advance the creative quality of the company's video and DVD production work.
The results of this comparison are presented in Table 1, where n, l, and s are the parameters which define the Gaussian blur modeled by the Toeplitz matrix H.
Examples include Curves, Selective Gaussian Blur Noise Reduction (SGBNR), and the new Dynamic Background Extraction (DBE) process.
This was due in large part to our successful attendance at the NAB tradeshow in Las Vegas where we conducted more than 100 private demonstrations of our new 844/X Version 2 software - dubbed The Finishing Release - and XBLUR - the world's first real-time, multi-stream Gaussian Blur.
Selecting the Background layer, I'll apply the Gaussian Blur filter with the radius set to a few pixels, which is usually enough to smooth the grain out of the color.
