Fiber Quantification #12

Open awhite40 opened 9 years ago

awhite40 commented 9 years ago

Objective:

  1. Find centers of fibers

    a. Segment with more values to remove edges of “fibers” in images

    i. So it means we will have to fit our histogram with more number of peaks.

    ii. We may have to play with number of bins also

    b. Labeling fibers bwlabeln - seperate individual fibers

    c. Compare with the confidence intervals - needs to be improved in the code

  2. Fiber orientation

    a. Gradients - help get straightness

    i. jacobian

    ii. try on sample image (one fiber)

  3. Image smoothing

    a. subtract images from shifted image

    b. matlab functions

    c. (subtracting average from image)*original

  4. Look for fibers that cross the volume

    volume of them will be related to processing condition

@tonyfast Here is a matlab function I was looking at for finding directionality. http://www.mathworks.com/matlabcentral/fileexchange/24409-hessian-based-frangi-vesselness-filter
