, it is often used to denote "standard deviation". The standard deviation of a Gaussian blur that represents the extended distance of the blur. Its default value is typically set to 1, and you can improve it to get a stronger effect.The E in the function is the Euler number (Euler's numbers), which generally takes a value of 2.7.

PS Fuzzy tool contains three tools-fuzzy tools, sharpening tools, smudge tools, these three tools can be the details of the image of the local decoration, in the correction of the image is very useful. The shortcut key for this tool is the letter R. Now let's take a look at how they are used and how they work. The Fuzzy tool of Photoshop Blur tool: As the name suggests, a tool that blurs the image with a brush. It works by reducing the contrast bet

HTML structure: Very simple, just an input, a div, can explain the problem on the OK; The results you want to achieve: 1, the input box to get focus when value is "", loss of focus value is "default value";-----This is a good realization; 2, when in the input box to search for content, click Div Search, request the console print output to search the content of elements (of course, each project needs different, here is just an example), and require the click does not affect the in

other elements, which is sometimes intolerable.. So here we propose solution 4 to get it through Div. onblur... but some problems also come along... First, because Div does not support the focus (non-ie) status by default, we cannot talk about blur. (Although ie supports it by default, blur is still not supported by default) An interesting method is to set tabindex to a natural value for div (of

This part has not been updated for more than a year. found that the level of code is much higher than a year ago: Since the use of vs2015, the waist is not sour, the leg does not hurt, a breath code hundreds of lines also do not bother. So the engineering code may need WIN10 SDK + VS2015 to compil

css| Filter If you use your hand to quickly cross an oil painting that has not yet dried, the picture will become blurred. The blur attribute under CSS will achieve this fuzzy effect.

The current application market, the use of hair glass effect of the app everywhere, such as the use of micro-letter voice chat can be found, voice chat page using a Gaussian blur effect. First look at the effect of the picture: With a closer look at the image above, we can see that the background image is based on the user's avatar as a Gaussian blur, which is used as the back color of the entire page.

. More worrying is that hackers or curious users can now easily get a variety of reverse engineering tools. Microsoft itself provides an MSIL disassembler, called ILDASM, free of charge, and there is a source code open. NET Decompile tool Anakrino; and, of course, many other vendors offer a commercialized reverse-engineering tool. First, modify the variable name The most effective way to prevent the threat of such reverse engineering is to blur it.

I am a beginner, if you find errors in the text, please leave a message to tell me, thank you Image Blur and smoothing is the same level of meaning, the smooth process is a vague process.The image denoising can be achieved by blurring and smoothing the image (image denoising and other methods) So how can you blur a picture?The image's fuzzy smoothing is the process of averaging the image matrix.
