When measuring the 'mean grey value' in imageJ, the software
Hello, When measuring the 'mean grey value' in imageJ, the software gives me only one mean value. Is it possible to access the values of each pixel it measured? Thank you very much for your help Youssef Chebli __________________________________________________________________ Looking for the perfect gift?

Youssef,
afaik the easiest way is to save your image as a "text image" and load this to a chart software such as MS Excel.

Would someone be so kind as to point me to instructions on how to add
text to a stack of images or a movie? I've done some web searching and scanned through the ImageJ documentation, but had no luck. Much thanks! Frank Shäffer Senior Research Engineer USDOE National Energy Technology Laboratory |
Hi Frank ,
I have done it for me. I am just taking graphics from image and then drawing string in that graphics mode. Then i saved images in jpeg format. The jpeg image consist of my string at location 50,50. same thing you can do for movie also because you have array of images. i think it will help you. Here imp is a ImagePlus object. try { BufferedImage bimg = null; Image img = imp.getImage(); int w = img.getWidth(null); int h = img.getHeight(null); bimg = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB); Graphics2D gg = bimg.createGraphics(); gg.drawImage(img, 0, 0, img.getWidth(null), img.getHeight(null), null); gg.dispose(); ////it writes into image that it is save from medsynaptic gg.drawString(""Hello text added",50,50); int ind = name.lastIndexOf("."); if (ind > 0) { String temp = name.substring(0, ind); File fi = new File(dir + File.separator + temp + ".JPEG"); ImageIO.write(bimg, "jpg", fi); bimg = null; img = null; } } ----- Original Message ----- From: "Franklin Shaffer" <[hidden email]> To: <[hidden email]> Sent: Thursday, December 04, 2008 3:00 AM Subject: adding text to stacks and movies?

Hi Frank,
what about the Time Stamper plugin? http://rsbweb.nih.gov/ij/plugins/stamper.html Michael ________________________________________________________________ On 4 Dec 2008, at 07:02, prashant wrote: > Would someone be so kind as to point me to instructions on how to add > text to a stack of images or a movie? > > I've done some web searching and scanned through the ImageJ > documentation, but had no luck. > > Much thanks! > > Frank Shäffer |

The Edit>Draw command in ImageJ 1.42b or later displays a "Process Stack?" dialog when operating on a stack. The Draw command works with area and line selections and with text created using the text tool. The Edit>Fill command also displays a "Process Stack?" dialog when operating on a stack. You can upgrade to the latest version of ImageJ (1.42c) using the Help>Update ImageJ command. -wayne |

Hi Youssef,
you can do almost anything regarding pixel values with a macro, however it will become a little more complicated, when you only want the values within some nonreactangular selection region. You can also configure the details the "Measurement" command gives you, if you only need some more info, besides MIn and Max, you can get statistics as Std Dev, Median and so on, it can be configured from the "Edit/Set Measurements" submenu of the results window.
