Blur effect on window background image

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-06 07:52:08
问题 I have a window with image as background. On that window I also have buttons and other controls. This is my style for that window: <Style x:Key="MyWindow" TargetType="{x:Type Window}"> <Setter Property="Background"> <Setter.Value> <ImageBrush ImageSource="Images\myImage.png" /> </Setter.Value> </Setter> <Setter Property="Effect"> <Setter.Value> <BlurEffect Radius="20" /> </Setter.Value> </Setter> </Style> The problem is that the blur effect is applied to the whole window and not just the

The blurring kernel of a low-quality camera

由 时光总嘲笑我的痴心妄想 提交于 2019-12-06 07:28:27
I am doing some image enhancement experiments so I take photos from my cheap camera. The camera has mosaic artifacts and all images look like grid. I think pillbox (out-of-focus) kernel and Gaussian kernel would not be the best candidates. Any suggestions? EDIT : Sample I suspect this cannot be done via a constant kernel, because the effects on pixels are not the same (so there are "grids"). The effects are non linear. (And probably non-stationary), so you cannot simply invert the convolution and enhance the image -- if you could, the camera chip would do it on-board. The best way to work out

Smoothing Mat of float with mask

由 纵然是瞬间 提交于 2019-12-06 07:25:33
问题 Is there a way to apply a Gaussianblur or median smoothing filter to a mat of floating points while supplying a mask of pixels that should be ignored? could you please help me? ty. 回答1: You can do this by: Zeroing out the regions outside the mask Smooth the image and the mask Divide each pixel in the smoothed image with the value of the smoothed mask The division in step 3 compensates for the black pixels introduced by masking. This works because the smoothed mask is darkened in the same way

CSS: Blur and invert colors for entire page

由 给你一囗甜甜゛ 提交于 2019-12-06 01:22:58
When using both webkit filters "blur" and "invert", only blur works. And if "blur" is removed "invert" works. Also only Chrome and Opera are responding to the code. Is there a way to make this work for recent IE and Firefox versions? body { -webkit-filter: invert(100%); -webkit-filter: blur(5px); -moz-filter: blur(5px); -o-filter: blur(5px); -ms-filter: blur(5px); filter: blur(5px); } You could use svg 's foreignObject element to import the entire body 's content into an svg element and then apply the filter s on the foreignObject which will apply the filter s on the entire body .

Avoid element blur handler when window blur invoked (browser loses focus)

由 不问归期 提交于 2019-12-05 18:26:22
问题 To expound upon the question: I've got an element which when clicked receives a sub-element. That sub-element is given a blur handler. What I would like is for that handler not to be invoked when the browser loses focus (on window blur). Towards that goal I've attempted several tacks, this being my current effort: function clicked() { // generate a child element ... field = $(this).children(":first"); $(window).blur(function () { field.unbind("blur"); }); $(window).focus(function () { field

UIVisualEffectView doesn't blur it's SKView superview

I'm writing a SpriteKit game and faced a problem with blurred view, which lies on the SKView. It is supposed to slide from the right when game is paused and it should blur the content of it's parent view (SKView) just like control center panel in iOS 7. Here is the desired appearance: What I actually get is: In fact the view on the left is not totally black, you can see how highlights from the superview are slightly struggling through almost opaque subview, but no blur is applied. Is it an iOS 8 bug/feature, or is it my mistake/misunderstanding Here is my UIVisualEffectView subclass's

Actions through WebDriver will not trigger the blur event

由 痴心易碎 提交于 2019-12-05 11:35:19
I have a web page with two dropdowns. Selecting an option in one dropdown will update the list of options in the other dropdown through a script that's triggered by the blur event. The blur event is triggered when the focus moves away from the first dropdown. This all works fine when navigating the page manually. However, when performing the same steps through WebDriver, the blur event is never triggered, and the dropdown is thus never updated, causing my script to fail. Here's the html for the dropdown I select first (and which has the onblur script attached to it: <select id="newOrder

CSS background blur on scroll

由 和自甴很熟 提交于 2019-12-05 06:33:04
I have fixed background image and upon scroll I want the image to go blur. I know how to do blur in css but do it at specific scroll position. Here is an example: https://medium.com/good-music/f160ba9e6c52 Any thoughts, examples, advice of snippets will be helpful. Thanks This codepen does exactly what you want. With browser support in mind it uses 2 images though instead of blur: http://codepen.io/sota0805/pen/pqLcv On your website example ( https://medium.com/good-music/f160ba9e6c52 ) there is no css "blur" effect . You can find one normal image: https://d262ilb51hltx0.cloudfront.net/max

Gaussian blur and FFT

问题 I´m trying to make an implementation of Gaussian blur for a school project. I need to make both a CPU and a GPU implementation to compare performance. I am not quite sure that I understand how Gaussian blur works. So one of my questions is if I have understood it correctly? Heres what I do now: I use the equation from wikipedia http://en.wikipedia.org/wiki/Gaussian_blur to calculate the filter. For 2d I take RGB of each pixel in the image and apply the filter to it by multiplying RGB of the
