Video Pre-processing DSP Software Design Based On DaVinci Processor

With continuous improvements of people's living standard and developments of embedded systems based on DSP processors, demands for video products based on DSP processors are growing. This paper discusses a video pre-processing software design based on DaVinci DSP to address these demands.Chapter 1 describes the progress of the video pre-processing system, analyzes the foundation of the digital video technology, and presents the evolution of DSP processors then puts forward the task of the subject and structure of this research paper.Chapter 2 describes the structure and functional characteristics of TI TMS320DM6437 DSP processor as well as the function of integrated development environment of CCS.Chapter 3 discusses the video capture and pre-processing technology in detail.Chapter 4 presents the design of an improved median filtering, and an image sharpening method.Chapter 5 divides the design into platform design and algorithm design, and focuses on video pre-processing software design based on DSP. Some related modules in platform design are discussed in detail, and an improved "two-stage" algorithm for filtering mixed noise is also discussed.Chapter 6 describes the video pre-processing DSP software optimization in detail.Chapter 7 summarizes the overall design and prospects for video pre-processing developments and applications.
