OpenCV

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.

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.

Detecting objects of interest in images has always been an interesting challenge in the realm of computer vision, and many approaches have been developed over recent years. As mobile platforms are becoming increasingly powerful, now is the perfect opportunity to develop interesting mobile applications that take advantages of these algorithms. This article walks us through the process of building a simple iOS application for detecting objects in images.

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.
