Unlike Haralick texture features that compute a global representation of texture based on the Gray Level Co-occurrence Matrix, LBPs instead compute a local representation of texture. in their 2002 paper, Multiresolution Grayscale and Rotation Invariant Texture Classification with Local Binary Patterns(although the concept of LBPs were introduced as early as 1993).

Local Binary Patterns, or LBPs for short, are a texture descriptor made popular by the work of Ojala et al. If this sounds interesting to you, be sure to take a look and consider signing up for the next open enrollment! What are Local Binary Patterns? If you like this tutorial, there are over 29 lessons spanning 324 pages covering image descriptors (HOG, Haralick, Zernike, etc.), keypoint detectors (FAST, DoG, GFTT, etc.), and local invariant descriptors (SIFT, SURF, RootSIFT, etc.), inside the course.Īt the time of this writing, the PyImageSearch Gurus course also covers an additional 166 lessons and 1,291 pages including computer vision topics such as face recognition, deep learning, automatic license plate recognition, and training your own custom object detectors, just to name a few. While the lesson in PyImageSearch Gurus goes into a lot more detail than what this tutorial does, I still wanted to give you a taste of what PyImageSearch Gurus - my magnum opus on computer vision - has in store for you. The majority of this blog post on texture and pattern recognition is based on the Local Binary Patterns lesson inside the PyImageSearch Gurus course. Looking for the source code to this post?

Read on to find out more about Local Binary Patterns and how they can be used for texture classification. In the remainder of this blog post I’ll show you how to use the Local Binary Patterns image descriptor (along with a bit of machine learning) to automatically classify and identify textures and patterns in images (such as the texture/pattern of wrapping paper, cake icing, or candles, for instance). Since today is both a Monday (when new PyImageSearch blog posts are published) and my birthday (two events that will not coincide again until 2020), I’ve decided to put together a really great tutorial on texture and pattern recognition in images. In order to rekindle some of that “little kid excitement”, I want to do something special with today’s post. And to be totally honest with you, I guess I’m a bit nervous about turning the “Big 3-0” in a few short years. Or buy alcohol.īut now as an adult, I don’t care too much for my birthday - I suppose it’s just another reminder of the passage of time and how it can’t be stopped. It was another year closer to being able to drive a car. Today is my 27th birthday.Īs a kid I was always super excited about my birthday. Click here to download the source code to this post
