This article explains how to use Nokia Imaging SDK to create powerful image editing applications. In this particular application, a user can select part of the picture by 'painting' over it and apply filter only to painted region. Then the filtered region can be blended back onto the image to create interesting images.

Introduction

Nokia Imaging SDK brings set of powerful filters which, either alone or combined, can create wonderful images. Applications that rely on filtering technology (e.g. Instagram) apply filters to entire images in order to make them more appealing. By using a different approach, a user can create interesting images by applying filters to arbitrary regions and then applying filters to just that region. Afterwards, that part is blended back into image and images can now feature one or more differently filtered regions. In this article we will show the technical details behind building such application and several examples of interesting effects will be shown.

Summary

Nokia Imaging SDK is a powerful tool that can be harnessed in different ways. I hope that this interesting approach to building complex compositions yields interesting applications that go beyond the simple "filter and share" applications. Since the application described here applies filters to just part certain part of the image (or consider applying filter everywhere but on some special part), resulting images can have surreal or hyper-real feel.
