　　Blur (blur) filters are used to soften a selection or image, and to dilute the boundaries of different colors in an image to mask the defect or create special effects. 　　1, Motion Blur (dynamic blur filter) Function: Blur the image in the specified direction (-360 degree

Http://www.cnblogs.com/xiaofeixiang/p/5129074.htmliOS development sometimes need to blur the picture, or by clicking the drop-down method, to remove the blur, everything is for the application more popular with users, after iOS7 translucent blur effect to get a large range of use of the relatively large, and now can see a lot of applications to use the image

Gaussian Blur is an image fuzzy filter that calculates the transformation of each pixel in an image with a normal distribution. N-dimensional normal distribution equation is In a two-dimensional space defined as where R is the fuzzy radius (r2 = u2 + v2), Σ is the standard deviation of the normal distribution. In a two-dimensional space, the contours of the surface generated by this formula are concentric circles that begin

Reading Tips: 《Delphi Image ProcessingThe series focuses on efficiency. The general code is Pascal, and the core code is BaSm. The C ++ image processing series focuses on code clarity and readability, all using C ++ code. Make sure that the two items are consistent and can be compared with each other. The code in this article must include the imagedata. Pas unit in "Delphi Image Processing-data type and public process. Image surface blur is a new fun

What is Gauss Blur? Gaussian Blur (English: Gaussian Blur), also known as Gaussian smoothing, is widely used in image processing software such as Adobe Photoshop, GIMP, and Paint.NET, which is often used to reduce image noise and reduce the level of detail. The image produced by this fuzzy technique, whose visual effects are seen through a translucent screen, is

IOS picture background blur effect 1. Using the blur filter in CoreimageThe original is as follows:Implementation of Coreimage:- (void) Viewdidload {[Super Viewdidload];Additional setup after loading the view, typically from a nib.UIImage * image = [UIImage imagenamed:@"Icon"];/*.. Blur effect filter in Coreimage: */Ciimage, equivalent to UIImage, functions for a

The Blur effect (blureffect) and Shadow effect (Dropshadoweffect) are two very useful and commonly used two effects, such as in the development album, you can add a blur effect to the thumbnail image of the photo, Dynamically change the size of the photo and blur the transparency to achieve a magnified transparency as you zoom in on the photo.First, fuzzy effect

The recent project design needs to use a slightly more blurred picture, so I went to Baidu search, treatment is probably the use of the Artifact PS (Flowers thousand bones See more, hehe). But in the eyes of a program ape, code can do everything. Below I will implement an Android Gaussian blur.Gaussian Blur: Gaussian blur (Gaussian Blur) is an image processing so

Android for Gaussian Blur effect and low version compatibilityHello, long time no see, long time No blog, summed up the following reasons have three, first, become lazy, second, become lazy, third, or become lazy, because any don't update blog reason is an excuse!first, the effect demonstrationThe project uses the Gaussian blur effect, consulted some data, considering the performance problem is finally choo

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

Reprint please keep the original link: http://write.blog.csdn.net/postedit/42400825Today's microblog, circle of friends, all kinds of social platforms are filled with photos, selfies or a variety of life records also take photos as their main means, visible photos of the importance of life, so the image processing software almost become one of the necessary software.Because people have a large demand for picture processing, I hope to develop a mobile phone image processing software that can be u

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

I have been working on the implementation of Image Blur effects on android a few days ago! I can't find a method until I can see that others call JNI, but I am not familiar with JNI! I have to start from scratch! Here we will not talk about JNI platform construction, but only about the key code of JNI. I will share the specific project with you! I did not find C ++ to blur images in JNI, so I had to write C

If you don't have the financial ability to buy a big aperture lens, you can play with the blur filter in Photoshop. Lens blur Filter is a very interesting filter, it can well simulate the depth of the lens effect. Do the lens blur to do layer mask or channel mask, otherwise and other fuzzy no difference. Below use two scenery photograph examples to explain lens
