You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
I publish a brand new Computer Vision, Deep Learning, and OpenCV tutorial every Monday at 10AM EST. Here you'll find my most recent tutorials and guides.
We’re getting closer to finishing up our real-life Pokedex! In my previous blog post, I showed you how to find a Game Boy screen in an image using Python and OpenCV. This post will show you how to apply warping…

Quick question. How does a Pokedex work? Well, you simply point it a Pokemon, the Pokedex examines its physical characteristics, and the Pokemon is identified instantly. In this case, our smartphone camera is our “Pokedex”. We point our smartphone at…

So, how is our Pokedex going to “know” what Pokemon is in an image? How are we going to describe each Pokemon? Are we going to characterize the color of the Pokemon? The texture? Or the shape? Well, do you…

What if we could build a real life Pokedex? You know, just like Ash Ketchum — point your Pokedex at a Pokemon (or in this case, snap a photo of a Pokemon), identify it, and get its stats. While this…

So you’re telling me that we are going to build a Pokedex in Python that can visually recognize Pokemon? Just like in the TV show? – Ash Ketchum Yes, Ash. That’s exactly what I’m telling you. The next series of…

If you haven’t noticed, the term “feature vector” is used quite often in this blog. And while we’ve seen it a lot, I wanted to dedicate an entire post to defining what exactly a feature vector is. What is an…

We are now at the final step of building an image search engine — accepting a query image and performing an actual search. Let’s take a second to review how we got here: Step 1: Defining Your Image Descriptor. Before we…

I’ve been throwing around the idea of writing a book for the past few months, but I wasn’t sure on what the exact focus was going to be. I’ve given it a ton of thought, worked out the specifics, and…

First, let’s have a quick review. Two weeks ago we explored the first step of building an image search engine: Defining Your Image Descriptor. We explored three aspects of an image that can easily be described: color, texture, and shape.…
