You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
The watershed algorithm is a classic algorithm used for segmentation and is especially useful when extracting touching or overlapping objects in images, such as the coins in the figure above. Using traditional image processing methods such as thresholding and contour…

Today’s blog post will build on what we learned from last week: how to construct an image scraper using Python + Scrapy to scrape ~4,000 Time magazine cover images. So now that we have this dataset, what are we going…

Did you know that the human eye perceives color and luminance differently than the sensor on your smartphone or digital camera? You see, when twice the number of photons hit the sensor of a digital camera, it receives twice the…

Today’s blog post comes straight out of the PyImageSearch Gurus course. Inside PyImageSearch Gurus we have a community page (much like a combination of forums + Q&A + StackOverflow) where we discuss a variety of computer vision topics, ask questions,…

Today marks the 100th blog post on PyImageSearch. 100 posts. It’s hard to believe it, but it’s true. When I started PyImageSearch back in January of 2014, I had no idea what the blog would turn into. I didn’t know…

A few weeks ago I introduced bat-country, my implementation of a lightweight, extendible, easy to use Python package for deep dreaming and inceptionism. The reception of the library was very good, so I decided that it would be interesting to…

One of the main benefits of the bat-country Python package for deep dreaming and visualization is its ease of use, extensibility, and customization. And let me tell you, that customization really came in handy last Friday when the Google Research…
