QR codes can store different types of data. Recently, I was involved in a project that a robot had to detect and decode pre-installed QR codes to refine its position. This post explains how I got 10 FPS performance on a Raspberry Pi Zero.

When I was coding in Matlab, there were some techniques to boost the execution time. Predefining the matrix size, using vectorization and importing C codes via Matlab Executable (.MEX) files were some of the well-known solutions. Similar solutions exist for Python codes. But the story is somewhat different with C++. This comes from the fact […]

When it comes to embedded computer vision, fractions of code acceleration are regarded as a huge success for programmers. Today, I’ll explain how to build a customized OpenCV for Raspberry Pi as one of the most famous single board computers. By following these simple tips, you’ll experience a 2-3x faster OpenCV on your board.

Raspberry Pi3 and Nvidia Jetson TX2 are two popular single-board computers for computer vision tasks. The standard way to use these boards is to attach USB mouse and keyboard with HDMI screen. But there are many cases where these devices are not available. This post explains how to use your laptop’s screen, mouse and keyboard […]
