    Excellent video. The explanations are so clear, even for someone without a background in microscopy.

    Glad I found your tutorials! Could you explain what we would have to do to do this for all stacks in a Z-projection? Does the read in variable in that case have another index that keeps track of stack that we could access?

    • @ZEISS_arivis
      @ZEISS_arivis  4 года назад

      Yes, absolutely. When you read in an image stack the numpy array includes extra dimension for the z position. For multidimensional tif images (e.g. z stack) please use tifffile library to read images. Also, for this method, you need to work with one slice in the stack at a time so when writing code you will have to keep this in mind.

      @@ZEISS_arivis Thanks for the reply! all makes sense, but i'm curious whether we will be able to avoid overcounting nuclei present in multiple stacks?

    Dear Professor,
    I am really enjoying and learning a lot from your lectures.
    I was wondering,
    Where can I get the images you use in your tutorial?
    Warm wishes, Eitan

    Thanks alot for your informative and well-explained tutorials. I have a question. I read a DICOM file and then want to do the segmentation on it. My question is that how should I save the DICOM file I read as volumetric data, to be able to do segmentation and thresholding on it?
    I am asking you this question because I save itas png, and. now I am not able to even have histogram for it.

    how to apply lagrange interpolation method to image?

    • @ZEISS_arivis
      @ZEISS_arivis  3 года назад

      I never found the need to use Lagrange interpolation for an image. But I do know that it is available in the scipy library. I am aware of this method to be a way of interpolating if you know the polynomial but I am not sure how you'd represent an image or image patches as a polynomial.

      Advantages and disadvantages of what? If you are inquiring about thresholding and segmentation then the simple answer is that thresholding is just a way of segmenting images.
