A real-time shot cut detector: Hardware implementation

With the enormous growth in digital audiovisual (AV) information in our life, there is an important need for tools which enable describing the AV content information. In this context, the MPEG-7 standard was developed in order to provide a set of standardized description tools which generate metadata about AV content. However, before any content-based manipulations, the hierarchical structure of video must be determined. This process is known as shot boundary detection or in other case scene change detection. In this paper, an old and reliable method based on local histogram has been used to implement shot cut detector for real-time applications. Since software implementation on PC is not suitable for this algorithm due to the sequential treatments of the processor, we have used an FPGA-based platform.
