PHP uses Gaussian algorithm to implement image Blur function example

In this paper, we describe the fuzzy processing function of PHP using Gauss algorithm to realize image. Share to everyone for your reference, as follows:

<?phpclass image_blur{function Gaussian_blur ($srcImg, $savepath =null, $savename =null, $blurFactor =3) {$    Gdimageresource= $this->image_create_from_ext ($SRCIMG);    $SRCIMGOBJ = $this->blur ($gdImageResource, $blurFactor);    $temp = PathInfo ($SRCIMG);    $name = $temp [' basename '];    $path = $temp [' dirname '];    $exte = $temp [' extension ']; $savename = $savename?    $savename: $name; $savepath = $savepath?    $savepath: $path; $savefile = $savepath. ' /'.    $savename;    $srcinfo = @getimagesize ($SRCIMG);      Switch ($srcinfo [2]) {case1:imagegif ($SRCIMGOBJ, $savefile); break; Case2:imagejpeg ($SRCIMGOBJ, $savefile);      Break Case3:imagepng ($SRCIMGOBJ, $savefile);      Break Default:return ' save failed ';    Save failed} return $savefile;  Imagedestroy ($SRCIMGOBJ); }} $image _blur = new Image_blur (),//blurfactor value represents the degree of ambiguity, Savepath is directly overwritten when empty, Savename is empty directly with the original original $image_blur->gaussian_ Blur ($srcImg = "./5.jpg", $savepath =null, $savename =null, $blurFactor =5);? >

This method Baidu to, there is an interview I let me do, Baidu a pile of data to achieve.

The value of Blurfactor represents the degree of ambiguity

Effect Show:

Original:



Degree of ambiguity 2



Degree of ambiguity 3



Degree of ambiguity 4



Degree of ambiguity 5



Degree of ambiguity 6



Degree of ambiguity 7
