Is there any command that can find the orientation of skeletonized image? like the attached image that average angle of lines with respect to horizontal line.

Answer 1

You can use houghlines to get the endpoints of all the line segments in the image. From that, you can easily calculate their slopes.

Can you explain bit more?

Can you explain bit more?

Once you have the end points (x1,y1) and (x2,y2) of a line, you can calculate its angle according to,

angle = atan2d(y2-y1,x2-x1)

Answer 2

You can write your own function:

• use imline to create a line
• draw a line aligned with horizontal/vertical one
• calculate the angle
• rotate image

@darova

What you mean by creating the line? I already have the line and want to find the angle of all lines in the above image.
