I'm working on a project involving enlisting a large number of relatively unskilled workers to do repetitive image analysis using ImageJ. I've written a set of macros which walk them through the analysis process, but in order to increase throughput and reduce errors, I'd like to figure out how to hide as much of the gui/menu interface as...
Hi, I have problem with Harris corner detection algorithm in ImageJ. Some info about it: http://www.cim.mcgill.ca/~dparks/CornerDetector/harris.htm I use Sobel filter for each block 3x3 to get differentials. I get only negative R[][] (C(x,y) from the link) factors. I can't find mistake, plz help. Part of the code: int w = ip.getW...
I need to save and re-load thousands of ROI polygons on a stack of images, actually a 30-frame-per second movie for 30+ minutes, so at least 54,000 frames. There can be multiple ROIs on a single image (frame) in the stack, and the size and number of vertices for each ROI is different. The ROI polygons are tracking the edges of shapes a...
There is a good function that I need, which is implemented in Java program: ImageJ I need to understand the algorithm used there. The function has several parameters: link text And before using FFT it converts image to a special one: The Bandpass Filter uses a special algorithm to reduce edge artifacts (before the Fourier transform, th...
I want to use ImageJ to do some processing of several thousand images. Is there a way to take any general imageJ plugin and apply it to hundreds of images automatically? For example, say I want to take my thousand images and apply a polar transformation to each--- A polar transformation plugin for ImageJ can be found here: http://rsb...
Hi everyone, I'm writing a little plugin for imageJ and I am drawing several regions as an overlay on the image. I'm using this code: ImagePlus imp = getImage(); Overlay ov = new Overlay(); for (int r=0; r<regions.length; r++) { ov.add(regions[r]); } imp.setOverlay(ov); Where regions is an array of Roi. This works as in...
Dear all, I am on a project where I am interested in the spacing & distribution of point objects in an microscope image. So the image consists of darker, circular small dots from a rather complex background. It would be nice to do this with an feature extraction script automatically some day, but for now I am just hand-picking the poi...
The code is in the String, example: String str = "IJ.run(\"FJ Edges\", \"\");"; If str is executed, the corresponding contents will run. ...
