Create and contribute a cool custom filter/effect or filter recipe to win DVLUP points and XP - or even a brand new Nokia Lumia 630. All qualifying contributions win!

ThresholdFilter

The Nokia Imaging SDK allows developers to create new effects by combining the built-in effects and filters into filter recipes, or by writing completely new custom effects in C# or C++. The community have already contributed some useful and interesting filter recipes and custom effects.

In this challenge we're asking you to contribute your own new (or significantly improved) recipes and custom effects to the wiki. At the end of the challenge, all of the qualified contributed filters will be added to the Nokia Developer Community Project on Github so that the whole community can benefit.

All qualifying contributors will get 100 DVLUP Participation Points and XP (XP contributes to your DVLUP reputation, while points can be redeemed for exciting DVLUP prizes). There will be a a heap more points/XP for the three best effects of each of three categories (filter recipes, C# custom effects, C++ custom effects). The authors of the most popular filter of each type, as selected by Twitter, will be among the first people to receive a Nokia Lumia 630!

We can't wait to see what sort of funky and innovative filters you can come up with.

Contents

Getting Started

The Nokia Developer Wiki is already home to an unparalleled set of developer-created Custom Effects and Filter Recipes. Check out the existing articles and effects before you start.

In particular:

The Nokia Imaging SDK (download here) comes with great documentation and examples, which you can find in the Lumia Developer's Library. In particular, the following documents explain how to work with custom effects and filters:

If you are new to the wiki, you can read Help:Wiki Editing Quickstart for help getting started.

How to participate

Create an original Nokia Imaging SDK custom effect (in C# or C++) or filter recipe.

Your filter should contain original content that enhances the existing available Nokia Imaging SDK filters documented in the Wiki and documentation libraries. It may create a new visual effect, or it may provide a significantly more efficient implementation of an existing visual effect.

To make it interesting we will be breaking the competition into three segments and awarding the prizes as we go. Filters that don't win the first segment will still be eligible for subsequent sections - so there is a benefit to contributing early and improving your filter(s) as the competition progresses.

The prizes

We will be awarding 100 DVLUP Participation Points and XP to all qualifying contributors in this competition.

At the close of the contest, the top article in each category will be selected via popular vote over Twitter. See the full terms and conditions to the Wiki Challenge for details about how this will work. The author of the top-voted article in each category will receive a Nokia Lumia 630!

In addition, winning a Nokia Developer Challenge gives you instant fame and kudos in the community and promotion through Nokia Developer channels. It also looks really great on your CV!

Note:

  • Unless prohibited by local law in the jurisdiction where you live, the device prizes are supplied under a "Device Access Services" warranty. In essence devices are covered by a "manufacturer fault" replacement warranty for 6 months from delivery of the original device.

Evaluation of entries

Entries are judged first and foremost by the usefulness, quality and presentation of their technical information. Multiple entries are encouraged but will be assessed on their individual merits - so a single great entry will win over multiple articles that are not as good. Each contributor may win a maximum of one prize and/or 500 DVLUP Points and XP per Wiki Challenge.

The entries will be judged by the Wiki Moderation team and selected Nokia technical experts after the Challenge period. The results for the Challenge are expected to be announced three weeks after the end of the Challenge.
