App extensions allow you to perform various actions without running an app: share photos on Facebook, send files as an e-mail attachment or open an article. If you are developing an iPhone app and want to find out more, keep reading and learn how to add extensions to iOS apps!

In the last Android development tutorial we’ve cover light source detection using OpenCV. This time we’ll cover edge detection, which allows us to distinguish objects from background. This task is usually the starting point to more advanced content analysis (e.g. determining object features, quantities etc.).

In the last Android development tutorial we’ve covered drawing a histogram using OpenCV. This time we’ll show you how to detect light sources in an image. This feature comes in very handy when building an Android app that has to perform quality checks on user-generated photographs (e.g. sending documents for proof).

In the last tutorial we’ve covered OpenCV and Android Studio project integration. This time we’ll try to make actual use of this setup. A code sample that we’ve used in a commercial Android application can be found on our GitHub page.

Cutting corners isn’t always easy, especially when you want to maintain decent quality. Even with a perfect cost estimate, there is plenty of room for unplanned expenses that can ruin your finances. The following article will show you how to avoid them during iOS, Android or Windows Phone app development.

Are you building an Android app to detect if a photo is blurry or overexposed? Then you should definitely try OpenCV: the library, which provides extensive solutions for analysing and processing photographs. If you’re interested in knowing how to add OpenCV to your project in Android Studio, keep on reading.

It is a quite common scenario when a client approaches us with their idea and asks for an exact project costs evaluation. As a requirement, he wants the project to be developed in line with Agile software development methodologies because he was told it is the best way to go. Faced with two contradictory requirements, one can’t help but wonder: Can you combine a fixed price approach with the agile SCRUM methodology?
