Object Detection Using OpenCV and Swift

by Josip Bernat

Swift is great, but what if your application relies on a library that’s written using C++? Luckily Objective-C++ is here to save the day. In this article, Toptal Freelance Swift Developer Josip Bernat integrates C++ code with Swift by using wrapper classes as a bridge and then creates an app that recognizes the Toptal logo using OpenCV.

Intro to Python Image Processing in Computational Photography

by Radu Balaban

Computational photography is about enhancing the photographic process with computation. While we normally tend to think that this applies only to post-processing the end result (similar to photo editing), the possibilities are much richer since computation can be enabled at every step of the photographic process—starting with scene illumination. In this article, Toptal OpenCV Expert Radu Balaban walks us through two examples of computational photography: low light and high dynamic range.

Computational Geometry in Python: From Theory to Application

by Charles Marsh

When people think computational geometry, in my experience, they typically think one of two things: 1. Wow, that sounds complicated. 2. Oh yeah, convex hull. In this post, I'd like to shed some light on computational geometry, starting with a brief overview of the subject before moving into some practical advice based on my own experiences in computational geometric programming with Python.
