blur

问题 I have this almost working bit: http://jsfiddle.net/HFzkW/ My code looks like this: <div id="cform-container"> <div class="alignleft" id="cform"> <form action="<?php print site_url('/sent'); ?>" method="POST" > <input type="hidden" name="Contact-Form" value="contact-form" /> <div class="cform-row"> <div class="alignleft cform-label"><label for="yn">Your Name</label><span id="star5">*</span></div> <div class="alignright cform-ti"><input type="text" name="yn" id="yn" /><br /><span id="namespan"

问题 I have this code (revisited version of this): void HessianDetector::detectOctaveKeypoints(const Mat &firstLevel, ...) { vector<Mat> blurs (par.numberOfScales+3, Mat()); blurs[1] = firstLevel; for (int i = 1; i < par.numberOfScales+2; i++){ float sigma = par.sigmas[i]* sqrt(sigmaStep * sigmaStep - 1.0f); blurs[i+1] = gaussianBlur(blurs[i], sigma); } ... Where: Mat gaussianBlur(const Mat input, const float sigma) { Mat ret(input.rows, input.cols, input.type()); int size = (int)(2.0 * 3.0 *

问题 I have a blur function attached to my ckeditor like so editor = CKEDITOR.instances.fck; editor.on("blur",function(e){ alert("hello"); }); you with me ? now when I click on the flash button the editor blurs and causes the alert to show. how to I stop that from happening and still get the alert to appear other times like when the user leave the editor area thanks again 回答1: As long as we're working on hacks, here's what I like to use to solve this problem. The key is that CKE uses iFrames for

问题 That's is question is in the title of this post, but anyway: I use the JFreeChart to create chart in my app. And one of requirement is a soft blured shadow instead solid, which is presented by default. I know I can add my image instead the default shadow, using setShadowPaint(Paint paint); but this way implies the creating blured image and adding it to the my report. Is there built case to achive needed effect ? Thanks for all. 回答1: There's nothing built-in, but you can use a ConvolveOp to

问题 I have this vert/frag shader, which is using vertex data and two textures. I am trying to apply post blur effect, but having only rectangles after it. vert: attribute float type; attribute float size; attribute float phase; attribute float increment; uniform float time; uniform vec2 resolution; uniform sampler2D textureA; uniform sampler2D textureB; varying float t; void main() { t = type; vec4 mvPosition = modelViewMatrix * vec4(position, 1.0 ); if(t == 0.) { gl_PointSize = size * 0.8; }

问题 I'm new in image analysis (with Python) and I would like to apply the richardson_lucy deconvolution (from skimage) on my data (CT scans). For this reason, I estimated the PSF in "number of voxels" by means of a specific software. Its value is roughly 6.73 voxels, but I don't know how to use it as a paramter in the function. The function uses the PSF parameter as a ndarray, so I tried in this way: from skimage import io from pylab import array img = io.imread ("Slice1.tif") import skimage

问题 So I have this form and I would like to do some stuff when the inputs loose focus. This is the code I have and it's working like a champ in every browser except Internet Explorer. function formstyle() { var focus = 0; //comentario is the ID of the input $("#comentario").focus(function() { //blablablabla }); $("#comentario").blur(function() { setTimeout(function() { var whatFocus = document.activeElement.tagName; if (whatFocus === "BODY") { focus = 0; //bla bla bla } }, 2); }); } $(document)

问题 I'm on MacOSX running this http://jsfiddle.net/q84wv/ on Chrome latest version. It won't work, while running that on Firefox it works perfectly, any clue? 回答1: Assuming that you want the alert() to be triggered either when the user tabs out from the anchor, or completes a click event, this should work: $('.menu a').on('blur mouseup',function(){ alert('oh'); }); Check this jsFiddle. It really depends what you're classing as blur here. If you're wanting it to trigger whenever the user's mouse

问题 I want to blur image with Gaussian blur algorithm. And I use the following shaders: Vertex shader attribute vec4 position; attribute vec4 inputTextureCoordinate; const int GAUSSIAN_SAMPLES = 9; uniform float texelWidthOffset; uniform float texelHeightOffset; varying vec2 textureCoordinate; varying vec2 blurCoordinates[GAUSSIAN_SAMPLES]; void main() { gl_Position = position; textureCoordinate = inputTextureCoordinate.xy; // Calculate the positions for the blur int multiplier = 0; vec2 blurStep

问题 I have a border, i want the background of this border to be partially transparent (opacity 0.8) but i do not want the image behind it to be well defined. The effect i am after is similar to the Windows Vista window border effect, where you can see that something is behind it but you cant tell what it is. A few clarifications: I am working on Windows XP, so i cant use Vista Glass I need this solution to be portable across any windows platform Any help would be appreciated :) 回答1: Extend Glass
