## OpenCV Python Tutorial For Beginners 30 – Probabilistic Hough Transform using HoughLinesP in OpenCV

code –
In this video on OpenCV Python Tutorial For Beginners, we are going to see Probabilistic Hough Transform using HoughLinesP method in OpenCV.
OpenCV implements two kind of Hough Line Transforms
The Standard Hough Transform (HoughLines method)
The Probabilistic Hough Line Transform (HoughLinesP method)

lines=cv.HoughLinesP(image, rho, theta, threshold[, lines[, minLineLength[, maxLineGap]]])

rho : Distance resolution of the accumulator in pixels.

theta: Angle resolution of the accumulator in radians.

threshold:Accumulator threshold parameter. Only those lines are returned that get enough votes ( greater then threshold ).

minLineLength : Minimum length of line. Line segments shorter than this are rejected.
maxLineGap : Maximum allowed gap between line segments to treat them as a single line.

OpenCV is an image processing library created by Intel and later supported by Willow Garage and now maintained by Itseez. opencv is available on Mac, Windows, Linux. Works in C, C++, and Python.
it is Open Source and free. opencv is easy to use and install.

Starting with an overview of what the course will be covering, we move on to discussing morphological operations and practically learn how they work on images. We will then learn contrast enhancement using equalization and contrast limiting. Finally we will learn 3 methods to subtract the background from the video and implement them using OpenCV.

At the end of this course, you will have a firm grasp of Computer Vision techniques using OpenCV libraries. This course will be your gateway to the world of data science.

Feel the real power of Python and programming! The course offers you a unique approach of learning how to code by solving real world problems.

How can i get the rgb values of detected lines in an image?

why are we giving index value as 0 in line[0] inside the loop

Hi sir, I'm following all your videos… It's really awesome… Thanks for providing such tutorials…
Sir actually I got a task to compete within 25th August 2019… They have provided data set also for that machine learning model, which is to detect number plate…

Really nice video, waiting for your next video.

Is this is last lecture of OpenCv…?

I'm following all your videos since you uploaded the scala. It was really fantabulous. the only unique thing in you is when compared to other Youtuber. your providing more information with a short interval and its very very clear with the definition.
