    Default Gaussian blur

    Hi,

    can anyone help me with creation gaussian blur filter for set of images in ImageJ. I've a stack of images in ImageJ stack, and my task is to create 2D gaussian blur filter for this image stack and subsequently create 3D gaussian blur filter.

    Please hepl me, i don't know how to do it

    Or use JavaFX 2 which has a ready-made class: GaussianBlur (JavaFX 2.1)

    Default Re: Gaussian blur

    Thanks for suggestions. But the hardest problem, i can't go through is creating 3D gaussian blur filter. Do you know how it is with z-coordinate, or else, is there something like superposition principle? In creating 3D filter can i use 1D gaussian formula three times for each coordinate? Or is there something more to understand?

    Do you have true three dimensional pictures? Or are they just a stack of two dimensional pictures?

    kind regards,

    I have a stack of two dimensional images stored in ImageJ stack.

    I don't know what ImageJ is, but can't that 'stack' be treated as a pile of 2D images that you can process one by one?

    I don't know what are you exactly asking for.ImageJ is libary for signal processing. But i think that the z-coordinate can be specific coordinate of each image stored in stack. I don't know if is this right, but i think that if i have a stack of images and the z-coordinate is exact location of pixel in following or previous image. But i think i realy don't get a point of creating 3D gaussian blur filter for stack of images.

    I'm not asking for anything; you're the one who came with this question. To me it still isn't clear if you're dealing with a true three dimensional image or a pile of two dimensional images.

    Yes i'm dealing with pile of two dimensional images.
