Line Detection via Standard Hough Transform

Detects lines in binary images via Standard Hough Transform.

Function uses Standard Hough Transform to detect Lines in a binary image.
According to the Hough Transform, each pixel in image space corresponds to a line in Hough space and vise versa.This function uses
polar representation of lines i.e. x*cos(teta)+y*sin(teta)=p to detect
lines in binary image. upper left corner of image is the origin of polar coordinate system
Example :
[pdetect,tetadetect,Accumulator] = houghline(Imbinary,pstep,tetastep,thresh)
