During the last Netguru team dinner a friend showed me a neat feature of his fancy Samsung device - Gesture Control to Take a Selfie (detecting hand to take a selfie). For some time now I’ve been interested in machine learning and I thought of implementing this myself. To solve this problem I’ve used Object Detection API SSD MultiBox model using mobilenet feature map extractor pretrained on COCO(Common Objects in Context) dataset. Follow these steps to create a simple hand detection app and see the results of my experiment:

I’m amazed how much mobile developers despise SQL. It’s fast and efficient way of storing data, proven in battle in so many years. I guess the reason of that for many of them, myself included, is the way we were taught at universities.

Nowadays, technology is growing at an unprecedented rate – the trend concerns especially technologies related to mobile. This trend has been brought about by the continuous development of mobile devices and their software. It is also related to the newly emerging technological branches: Internet of Things (IoT), Augmented Reality (AR), Machine Learning, etc. In a company such as Netguru, it is extremely important to keep up-to-date with all the technological news and tools that could improve development. To accomplish this goal, we created two R&D teams: one for Android and one for iOS. Their task is to research and develop ideas based on new technologies and develop the skills of the developers so that they can provide the highest level of services.
