Filter In the practice of photography, the virtual background is a common means to highlight the main body. But because the actual focal length of the consumption-level DC lens is very short, it is more difficult to realize the shallow depth and blur the background. If we want to use a consumer-level DC can also achieve the virtual background of the main effect, then, Photoshop post-processing can be useful. The above effect picture, is using Photosho

Write in frontNow, more and more apps are using the blur effect, which is called Gaussian Blur. As we all know, fuzzy rendering on the Android platform is a fairly CPU-intensive operation, which is unavoidable once it is handled poorly. In general, given the efficiency, the best way to render a picture is to use OpenGL, followed by the use of C++/C, where Java code is the least efficient and the slowest. Bu

One, the effect demonstration The project used a Gaussian blur effect, looked over some data, considering the performance of the final choice to use the Android Renderscript Library to achieve, on the use of renderscript to achieve a Gaussian blur online there are many similar methods, most of the summary of the relatively chaotic, Here is to do a collation, for similar needs of students reference and lear

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

Including this year's latest release of IOS8 also follows this design, even in OS X version 10.10 Yosemite also began to use a large number of translucent blur.In iOS development, we have a lot of op

In the PS Fuzzy tool contains three tools--fuzzy tools, sharpening tools, smudge tools, these three tools to the details of the image of the local decoration, the following small series to tell you how they use and the effect. The Fuzzy tool of Photoshop Blur tool: A tool that blurs the image with a brush. It works by reducing the contrast between pixels. Fuzzy tools Task bar for Blur tool:

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. Let's take a look at the expression of the Blur property: Filter:blur (Add=add,direction,strength=strength) We see that the Blur property has three parameters: Add, direction, stren

convolution processes to perform Gaussian blur on the image. The processing effect is not bad, it feels okay to process small images, but it is still too slow to process large images, on my P4 2.8 GB and 1 GB memory machines, perform Gaussian fuzzy q = 3, r = 5 on 10 million pixel images, excluding image loading and pre-data conversion, the processing speed has never been significantly improved after several modifications. The main reason is the gene

Gaussian Blur is a two-dimensional convolutional fuzzy operation. In contrast to mean blur, Computing workload increases, but Gaussian Blur can achieve some special effects, especially in Image Noise (non-pretzels Noise) elimination has a very good effect. The one-dimensional Gaussian formula is as follows: X is an integer that specifies the range of [-N, N]. S

Blur Effects (Blureffect) and shadow Effects (Dropshadoweffect) are two very useful and commonly used two special effects, such as in the development album, you can add a blur to the thumbnail image, in the process of enlarging the photo dynamically change Change the size of the photo and blur the transparency to achieve a magnified transparency effect. I. Fuzzy

App design often uses some blur effect. iOS has now provided some fuzzy APIs that can make it easy for us to use. One is to use the core Image, and the other is to use the Vimage API in Accelerate.framework.Blur using the core imageThe Core image was applied early in the Mac system, and later the framework was applied to iOS, but it wasn't until iOS6.0 began to support Blur. This API is easy to call and con

is a blur of the value of a large case. At this point the solution is to direct the background-size:cover, to background-size:150% 150%, on the line. The effect chart is as follows: A closer look reveals that the white side is less obvious. The other is when the value of the blur is relatively small, such as the above blur value to 20, the

Not much nonsense, first. Source image Circular clear area Clear horizontal area Vertical clear area Hey, it looks okay ~~ The background we are talking about here is virtualized. Naturally, we cannot automatically identify the background and prospects. Therefore, it can only be regarded as a semi-automated process: Which region is clearly specified by users, which region is blurred, and then make a simple transition between a clear region and a blurred region. Here we provide three modes: C

The Blur event occurs when an element loses focus. The blur () function triggers the blur event, or if a function parameter is set, it can also specify the code that executes when the Blur event occurs. Tip: Earlier, the Blur event occurred only on form elements. In a new br
