What exactly are you trying to extract? The question title and the question itself seem to ask different things.<br />
If you threshold on the blue plane at 100 or so (assuming 3 8-bit color planes) it should separate the white from the black and red.

An algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.

Multimedia programming is the process of developing multimedia products, programs or services that combine text with sounds, pictures, graphics, video-clips, virtual reality, digital animation and other forms of media, and generally requires skill sets that include programming languages such as Java and C++, graphics, animation and video production.

Multimedia Programming

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
