Image and Video Processing in Real-time:
Erkennt man die Notwendigkeit einer Echtzeitforderung in seiner Bild- und Videoverarbeitung und sucht nach Wegen diese durch Ausnutzung inhärenter Parallelität in den Algorithmen zu erreichen, so ist zunächst der Begriff der Echtzeit zu klären.
Three interpretations of the concept of real-time can be discriminated:
Real-time in the perceptual sense describes the interaction between human and machines for an instantianeous response of the computer to the operator input, i.e. in image processing that the processing results is available immediately after the input without a perceivable delay.
Real-time in the software engineering sense defines a time-constrained response in order to avoid system failure, i.e. the logical correctness depends on the mathematical correctness of the results and their timeliness. Consequently, real-time indicates predictable performance than fast processing.
Real-time in the signal processing sense means termination of processing during the time period of subsequent sample values.
An image processing solution in real-time is almost a combination of adapted hardware and software.
Selection of hardware is the most important decision w.r.t. an appropriate computer platform out of a variety of options. The choice for a processor, e.g. GPP, DSP, FPGA, Media-Processor SoCs and GPU demonstrate just one level of decision for a dedicated hardware solution.
Concerning software it is important to design algorithms so that real-time deadlines will be met. Diverse software architectures in combination with memory management and program code optimization provide a variety of time-efficient solutions.
