Blur an image?

How do I blur an image or part of a clip?

use the text tool "pull focus" and delete the text so it is blank.
So split the clip you want to blur on both sides to the correct places. Then highlight it, and go to the text tools. Drag "pull focus" on top of it. Delete any text there so it is blank.
By using the dissolve transitions and other things, you can make the ends neater if you mess with it. Be creative and clever. You can make it work.

How do I change the blurred background image on the Select User Screen

I have changed the desktop image on all of my users, as well as the screen savers. However, when I logout of one user and the screen where you select another user comes up, there is an image on the background of this particular screen that I cannot figure out how to change.
This is crucial because I do not want to see my crazy, abusive ex-wife every time I select a different user...even if it is a blurred image.
This blurred out image does not appear anywhere else on any of the different user accounts as a background/desktop image.
How do I change this background image?
Please help.

This seems to be a bug that goes away w/ 10.10.1
Yosemite login screen possible bug
"if I put my Mac in sleep mode, when I wake up it, the password request screen uses the default Yosemite wallpaper in blurred mode instead of the wallpaper I have chosen for my desktop."
or maybe not:
"And it still happens after the 10.10.1 update."
This seems to work.
"The only way I was able to fix this problem was to go Mission Control and close all extra desktops I was using except Desktop 1 (which you cannot delete if it is the last one). After deleting the extra desktops besides Desktop 1, I went into preferences and set my wallpaper. Once I complete both of these steps I returned to the login screen. The wallpaper I used for Desktop 1 was now my background for the login screen. Hope this helps."

Change the amount of blur an image??

Hi everyone,
I'm trying to write an application to blur an image. I've created a set of five option buttons and clicking on each option button should make the image increasingly more blurred without making the image brighter or darker. The code that is executed whenteh user clicks on the first option button works fine - this one uses a three by three kernel. I thought that if I used a larger kernel for the next image it would make it more blurred?
The problem is the second one makes the image much darker.. How can I solve this? Am I right in thinking that bigger kernels will change the level of blur in the image?
float ninth = 1.0f/9.0f;
float[] kernelNinth = { ninth,ninth, ninth,
                           ninth,ninth, ninth,
                           ninth,ninth, ninth,};
float twentyFifth = 1.0f/25.0f;
float[] kernelTwentyFifth = { twentyFifth,twentyFifth, twentyFifth,twentyFifth,twentyFifth,
                          twentyFifth,twentyFifth, twentyFifth,twentyFifth,twentyFifth,
                          twentyFifth,twentyFifth, twentyFifth,twentyFifth,twentyFifth,
                          twentyFifth,twentyFifth, twentyFifth,twentyFifth,twentyFifth,
                          twentyFifth,twentyFifth, twentyFifth,twentyFifth,twentyFifth,};
public void itemStateChanged(ItemEvent e)
if (e.getSource()== optRate1)
     blur(kernelNinth);
else if (e.getSource()== optRate2)
     int i;
     float total=0f;
     for(i =0; i<25; i++)
        total+=twentyFifth;
     System.out.println("i: "+i);
     System.out.println("twentyFifth: "+twentyFifth);
     System.out.println("total: "+total);
     blur(kernelTwentyFifth);
   }This is the output:
i: 25
twentyFifth: 0.039999995
total: 1.0000001
Thanks very much for your help!

I'm sorry, but I can't help you with blurring images.
But I would propose to change the program a bit:
private float[] createPartKernel(int n){
float f = 1.0f / (float)n;
float[] kernelArray = new float[n * n];
for(int i=0; i<kernelArray.length; i++){
kernelArray[i] = f;
return kernelArray;
}That's all. Now you can try it with many more different kernels, without typing much.
Good luck for your blurring.

"Blurring an image" in FCP.

Hello,
In a recent short movie I shot, an image of a commercial product appears on our set. I need to "blur" this image out of the video for copyright purposes. Is there an easy way to this using FCP, e.g., Motion or LiveType, for instance?
Gary

Duplicate the clip you need to blur a part of and place it directly above the original in your timeline. Then add a garbage matte to it in FCP... blur the lower clip with a gaussian blur or other blur, and then use the garbage matte to cut in only what you want to be seen with the blur... if the shot moves, you can move the points of the garbage matte to move with the shot.

Blur an image - it just draws a black box!!

Hi,
I'm trying to write a method to blur an image and draw it on a panel. It just draws a black box (at least its the right width and height though!)
I'm not too familar with Graphics 2D so I've no idea what the problem is - I've looked at several examples and as far as I can see my code is the same..
This is the main class:
public void blur()
      currentImage = images[lsClips.getSelectedIndex()];
      int height=currentImage.getHeight(this);   //make new buffered image same width, height as original image
      int width=currentImage.getWidth(this);
      System.out.println("the width is"+width);
                                                   //convert original image to a buffered image
      BufferedImage srcBuffImg= new BufferedImage(width,height, BufferedImage.TYPE_INT_RGB);
      Graphics2D big = srcBuffImg.createGraphics();
      big.drawImage(srcBuffImg,0,0,processedImagePanel);
      processedImagePanel.setImage(srcBuffImg);
      processedImagePanel.repaint();
      processedImagePanel.revalidate();
}processedImagePanel is a customised JPanel class that I created to display the image on. I think that the setImage() method works propperly - the buffered image is not null when I checked it in this method. This is the setImage() and paintComponent() methods of that class.
public class ImagePanel extends JPanel
private BufferedImage buffImg;
float[] elements = { .1111f,.1111f, .1111f,
                      .1111f,.1111f, .1111f,
                      .1111f,.1111f, .1111f,};
public void setImage(BufferedImage img)
    processing = true;
    this.buffImg = img;
    this.repaint();
    this.revalidate();
protected void paintComponent(Graphics g)
    super.paintComponent(g); //paint background
    if(buffImg!=null )   //draws blurrred image
      System.out.println("DRAW Buffered img");
      Graphics2D g2 = (Graphics2D) g;
      int w = getSize().width;
      int h = getSize().height;
      int bw = buffImg.getWidth(this);
      int bh = buffImg.getHeight(this);
                    //create a buffered image for the processed image
     BufferedImage destBuffImg = new BufferedImage(bw,bh,BufferedImage.TYPE_INT_RGB);
     Kernel kernel = new Kernel(3,3,elements);
     ConvolveOp cop = new ConvolveOp(kernel,ConvolveOp.EDGE_NO_OP,null);
     cop.filter(buffImg,destBuffImg);
     g2.drawImage(buffImg,cop, 10,10);
}I would be very grateful if anyone could give me any suggestions..

BufferedImage srcBuffImg = new BufferedImage(width,height, BufferedImage.TYPE_INT_RGB);
Graphics2D big = srcBuffImg.createGraphics();
big.drawImage(srcBuffImg,0,0,processedImagePanel);
processedImagePanel.setImage(srcBuffImg);
processedImagePanel.repaint();
processedImagePanel.revalidate();I think the bug is here: why do you paint the (empty) buffered image in itself? I guess, you wanted to paint the currentImage to the bufferedImage.

How to blur an image?

Could someone please provide an example of the easiest way to blur an image. I have googled for it but I haven´t find any examples that made me more clear over how it works.
What classes do I need, except the Image class?
Thanks in advance!
EDIT: I have found this method:
public void blur() {
    float data[] = { 0.0f, -1.0f, -1.0f, 1.0f, 0.0f, 0.0f,
        0.0f, 0.0f, 0.0f };
    Kernel kernel = new Kernel(3, 3, data);
    ConvolveOp convolve = new ConvolveOp(kernel, ConvolveOp.EDGE_NO_OP,
        null);
    convolve.filter(biSrc, biDest);
    bi = biDest;
}I have tested changing the data[] array values and the image is getting blurred. But what kind of values are these 9 elements?

If you change the data[] array to something like this
float[] data = {1/9f,1/9f,1/9f,
                1/9f,1/9f,1/9f,
                1/9f,1/9f,1/9f}; then you would have stumbled upon one of the easiest ways to blur an image. A convolution just basically takes the above array and "places" it on the image. In the above case I have a 3x3 "window" that is moved across the image. At every point the pixels are multiplied with the corresponding value in the window and then added together. The sum becomes the new value for the center pixel.
So in the above case, I'm taking 1/9 of every pixel, summing them, and making the sum the center pixel. For a colored image this is done on all three channels (red, green, blue). The resulting image then has the property that every pixel has a little bit of its neighbors' colors. This achieves a blurring effect. Of course, there are more accurate (and still fast) ways to go about blurring, but a box-convolution where each array element is +1/size+ is probably the easiest.
Now as far as convolutions go, you can manipulate the values in the window or the dimensions of window to achieve various effects (median filter, primitive edge detection, sharpening, embossing, ect..). In fact, convolutions are so important to image processing that most computers have built in hardware to speed up the calculations. The ConvolveOp in core java tries to utilize this acceleration, but has certain annoying limitations.

Blurred print image

Fix for blurred print image on HP photosmart 4780 using adobe reader 11.0.03 on iMac OS X 10.6.8?

G.Hoffmann wrote:
The OP uses Photoshop as RIP for large format prints…
Is that what the OP's description means?
In my ignorance, I had imagined RIPs were magically sophisticated devices. So any application that rasterizes an image can be considered a proper "RIP"?
Yes I understand that RIP stands for Raster Image Processor/Processing, but I thought it needed to meet certain credentials to merit the acronym.

Blurring of images imported from photoshop?

I have latest version of iMovie and OS. When I import images from photoshop, I get blurring of the image and sometimes pixilation. I looks normal in the workspace viewer but when I play the timeline the image deteriorates.

Thanks for looking at my problem. When I looked carefully at the new name (thanks dj for telling me to do that) I realized that the name had parts of what I had added as a preset and applied in External Editing. What appears to have happened is that my original preset was corrupted and dropped out the part that told it to use the original file name. I have repaired it and now all is well. Thanks for the responses and the help! Much appreciated.

Blurred preview image when dragging playhead in Animation Timeline

Hi,
when I move the playhead (of the Animation Timeline) by hand back and forth, the image get's blurred untill I stop dragging. This is really annoying since I need to draw and animate some small shapes in pixel perfect manner and can't see the difference between the frames because of the blurred image.
It is not blurred when I use the "Go to Next Frame" buttons in the timeline window, but this is cumbersome as I have to quickly compare frames by going back and forth.
I understand that PS probably gives me a compressed version of the images so it can actually play the animation fast, but I am talking about a hand full of frames in low resolution (1000x1000) on a Macbook Pro Retina with 16 GB RAM!
My Performance setting are all up (90% RAM allocated to PS, enough free space on my SSD Hard Drive). I also tried different settings for the History and Cache.
Can anyone help?
Thanks!
Marek

OK, I found out the reason I wasn't hearing the sound when dragging the playhead was due to the fact that in the properties for the sound I had the Sync set
to Event, but I needed to set it to Stream. Then it works fine!

Blur an image...quickly!

I want to blur an 800x600 image repeatedly to give the impression that it's "losing focus." I know this isn't a trivial operation CPU-wise, but I'd like to get roughly 30 frames a second while doing this. Am I dreaming, or is this possible?
I'm running on a 2.8GHz (I think) PC with Java 1.4.2. I'm using ConvolveOp against a BufferedImage, and calling paintImmediately on the buffered image's graphics context after each successive ConvolveOp. Currently, I believe I'm getting something in the range of 5 frames a second.
What can I do to ensure that my code runs as fast as possible in Java? Would going to Java 1.5 make a significant difference? Is there something I should do to ensure my graphics accelerator is involved?
Thanks very much.

image effects in java definitively isn't fast as far as i know- maybe try having 4-5 translucent layers each containing the image and have them move in different directions? i dunno

Lock screen shows blurred background image with Safari run and volume controls

The normally sharp image in the lock screen is blurred. Run and volume controls for Safari are displayed at the top of the screen - volume slider moves, play button has no effect. I do not know how to return the screen to normal appearance. Wallpaper settings show normal image. There are no active movies or videos running.

OK, I returned to the settings for Wallpaper and Brightness and selected a different Wallpaper - the problem went away. The cause may be that the specific wallpaper I had been using is no longer present for selection.
