　　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

Gaussian blur principle, algorithmReference article: Some knowledge points of image convolution and filtering　　To learn Gaussian blur we first need to know some basic concepts:Basic concepts of linear filtering and convolutionlinear filtering can be said to be the most basic method of image processing, it can allow us to process the image, resulting in a lot of different effects. The practice is simple. Fir

Yesterday read the official document of Renderscript, found that renderscript this fellow is a bit of a kick. Accidentally found Scriptintrinsic this abstract class, some very useful subclasses. One of them is called the Scriptintrinsicblur class, which is basically the image to achieve a Gaussian blur. Scriptintrinsic's statement: Scriptintrinsicblur the declaration of the class: Coupled with a look at the next SDK in the samples, he wrote a G

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

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

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
