I have implemented the missing function "houghlines.m" for the image package.

This function extracts all line segments from a BW image, when given the results of a Hough transform (from the functions hough.m and houghpeaks.m).

The algorithm is a straigtforward implementation and might not be runtime optimal, yet. It uses the information from the Matlab help page and from the book (Gonzalez,Woods,Eddins) that Matlab mentions on its help page of the connected function houghpeaks.

You can find the new file on my bitbucket repository:

https://bitbucket.org/hgimpel/octave-image/commits/9425df685b4a80beda314a1d29487718664c1395

The file is on the default branch there, with the bookmark "new-houghlines" attached.

I will also add the function file (houghlines_V1.m) to this report.

I would be happy to hear comments or feedback on this.
