The Adobe® Pixel Bender™ technology delivers a common image and video processing infrastructure which provides automatic runtime optimization on heterogeneous hardware. You can use the Pixel Bender kernel language to implement image processing algorithms (filters or effects) in a hardware-independent manner. The Pixel Bender graph language is an XML-based language for combining individual pixel-processing operations (kernels) into more complex Pixel Bender filters.
The Pixel Bender Toolkit includes the Pixel Bender kernel language and graph language, the Pixel Bender Toolkit IDE (an integrated development environment for Pixel Bender), sample filters, and documentation.
Pixel Bender development offers many advantages:
Low learning curve - Pixel Bender offers a small number of tools that are sufficient to write complex image-processing algorithms. Learning Pixel Bender is easier than learning C/C++ and each application's plug-in SDK. You do not need to know any graphics shading language or multi-threading APIs.
Parallel processing - Pixel Bender allows the same filter to run efficiently on different GPU and CPU architectures, including multi-core and multiprocessor systems. It delivers excellent image processing performance in Adobe products.
Supports all bit-depths - The same kernel runs in 8-bit/16-bit/32-bit within the application.
Support by multiple Adobe applications - Pixel Bender is integrated with multiple Adobe applications . It allows you to develop filters that are portable among various Adobe products. There is an active Pixel Bender Exchange where developers share their filters.

Pixel Bender is best suited for the kind of algorithms in which processing of any pixel has minimum dependence on the values of other pixels. For example, you can efficiently write a kernel to manipulate brightness of the image because brightness of each pixel can be changed independently. You would not want to use Pixel Bender to compute a histogram, because a histogram requires the values of all the pixels in an image.
For more details, please see the Pixel Bender Developer's Guide and the Pixel Bender Reference included in the Pixel Bender Toolkit.
Adobe Pixel Bender prerelease 6 (version 1.5) expands on previous releases with the ability to create, compile, and preview Pixel Bender graphs in the Pixel Bender IDE. Prerelease 6 continues to support Pixel Bender filter processing in Adobe After Effects™ CS4, Flash Player 10 and Photoshop CS4.
