Vision processor system for moving-object analysis

A Flexible DSP-based Network for Real-Time Co-operative Windowing Applications

“…Two modules carry out the object detection, while the other 14 are reserved for object tracking, and the host computer performs the object motion interpretation. A similar configuration is described in Kubota et al [8], with 16 M68030-based processing ('local') modules, and a Sun Sparc 2 Station as a host computer. A special hardware ('overall') unit capable of parallel and pipeline processing is also used to carry out overall image processing.…”

“…For example, Lang et al [4] and Lee et al [5] used custom-built cameras with on board A/D converters and computers to acquire and process regions of interest within the image frame. The multiple window vision systems proposed by Graefe [6], Inoue and Mizogushi [7], and Kubota et al [8] include a common video bus for all of the window processors. The architecture proposed in this work is based on a high-speed digital camera, field-programmable gate arrays (FPGA), and a network of TMS320C40 digital signal processor (DSP) modules (Figure 1).…”

Robust structure from motion using motion parallax

“…In the present implementation 4 colour markers attached to a glove (figure 4) are tracked in real-time (25Hz) using purpose built image processing system for detecting and tracking image features [7]. The interpretation of the visual motion is carried out on a host workstation and its results are communicated to a graphics workstation which responds by changing the position and orientation of a computer graphics model (see figures 2,3,4,5).…”
