Hi,
I am trying to learn Local Binary Pattern with scikit-image and as I have
only limited knowledge in numpy and image analysis I find it hard. As a
result, I will appreciate a lot if you can provide me some answers as I am
sure that they will help me to advance:
- If I understand correctly the skimage.feature.local_binary_pattern(image,
P, R, method=' uniform) will go pixel by pixel (starting from pixel
location 1,2) and generate the binary number based on the P and R, am I
right?. If so what happens if the R is “out of boundary”?
- How do you calculate the histogram and why are there are 18 bins in the
example
(http://scikit-image.org/docs/dev/auto_examples/plot_local_binary_pattern.html)?
- The output is (N, M) array and when I look at it is not clear to me what
is the output and how do you generate a histogram from it, can someone you
please clarify it.
I know that these questions are be basic and while I was trying to look for
answers I found the information more mathematical and less with applied
approach. Therefore, any help, ideas or tips will help.
Thanks for the patience,
G.
