Lens Blur is a Nokia Developer example application demonstrating the use of two Nokia Imaging SDK APIs, Interactive Foreground Segmenter and Lens Blur Effect. Interactive Foreground Segmenter is first used to create a mask (foreground/background), after which Lens Blur Effect (also known as Bokeh) is applied to the areas that were marked as background. This Nokia example application has been created to provide tips and best practice guidance for software developers and app designers, and may not have all the features you would expect in a commercial product. This application is published in Store as a free software as it may also have value to regular Nokia phone users. The source code and documentation of this example can be downloaded from Nokia Developer website.
