How to convert a binary image into lines only

The image I have is on the left side and I am trying to turn in into lines only (possibly array of lines) as shown on the right image below.

Is it possible to achieve with hough transform and right settings?

Hi,

You can use the command “bwskel” for this purpose. It takes two parameters as input, the binary image and minimum branch length. For example,

result = bwskel(im, 'MinBranchLength', N); 

where “im” is the binary image and the parameter “N” is the minimum branch length i.e., “bwskel” prunes branches shorter than the specified “N”.

For more information on “bwskel”, you can refer to the following documentation:
