HTML5 video is blurry and low-contrast ONLY in my installation of Chrome

由 霸气de小男生 提交于 2019-12-11 15:29:23
问题 I am in Windows 7 x64, using Chrome 22. When I view an MP4 video in the video tag, it appears blurry and low-contrast compared to the source video viewed locally in Media Player Classic. A screen-measuring app shows that both players are displaying the video at exactly its native dimensions (400x300). This appears to be a problem only with my installation of Chrome. The video looks perfect on other machines, Macs and PCs alike. I have tried reinstalling Chrome, disabling all extensions,

Two instances of blur.js possible?

由 自闭症网瘾萝莉.ら 提交于 2019-12-08 07:49:05
问题 I would like to use blur.js on two different elements with different sources. How can I achieve that? My code so far: $('.blurry1').blurjs({ source: '.source1', cache: false, radius: 10, debug: 1, }); $('.blurry2').blurjs({ source: '.source2', cache: false, radius: 10, debug: 1, }); Only the second function is executed correctly. 回答1: It can be done but it’s a bit of a hack as it relies on the setTimeout function to wait until the first blurjs function has finished. $('#blurry1').blurjs({

CSS or JavaScript Div Blur magic

Okay, so a new version of the iCloud website is out. It has what appears to be some crazy voodoo Apple magic going on. They were able to blur the background icons behind the login screen, and I can't figure out how they did it. It's not a static image, as the icons change size if you resize the browser. Would someone please explain? https://www.icloud.com/ I think you can implement using css! please check out http://www.w3schools.com/svg/svg_fegaussianblur.asp You can use alot of different filters by declaring them like <filter id="f1" x="0" y="0"> <feGaussianBlur in="SourceGraphic"

OpenCV, Variation of the Laplacian (Java)

由 耗尽温柔 提交于 2019-12-05 12:04:20
I am attempting to locate the Variation for the Laplacian based on an image with the goal of getting a numerical value based on the blurriness of an image. This is a useful post http://www.pyimagesearch.com/2015/09/07/blur-detection-with-opencv/ cv2.Laplacian(image, cv2.CV_64F).var() I've been trying to implement the same without luck. My starting point is a byte[] representing the image (img): Mat mat = new Mat(img.getImageHeight(), img.getImageWidth(), CvType.CV_8UC3); Imgproc.cvtColor(mat, mat, Imgproc.COLOR_BGR2GRAY); mat.put(0, 0, putData.getFileContents()); Imgproc.Laplacian(mat,mat,

Blurry map tiles at start of android app based on google Maps API v2

由 ε祈祈猫儿з 提交于 2019-12-05 04:36:11
问题 I have an app including a Google Map APIv2. After starting the app the map tiles are blurry. (sometimes just some parts) The tiles are getting sharp, only when the user moves the mapview a little. Moving the mapview by code does not solve the problem. Any ideas? 回答1: I has similar issue where the map would render blurry/low fidelity until I dragged the map with finger. The issue I think was because I was updating the map with googleMap.animateCamera(cameraUpdate); once every second but I wasn

Android Blur View (Blur background behind the view)

问题 I am trying to make the bottom part of an Image blur for the view on top it like in the image. I tried blurring it using Rendenscript but I am not able to blur only the part behind the view. :( I have seen many libraries but almost all of them blur the entire image, but not a part of it. Also, an important part is that I am using this inside a ViewPager and hence needs to be fast and dynamic something like this in IOS which redraws itself the moment image behind it changes. Any help is
