  • Patent number: 8538080
    Abstract: In a flame identification method and device for identifying any flame image in a plurality of frames captured consecutively from a monitored area, for each image frame, intensity foreground pixels are obtained based on intensity values of pixels, a fire-like image region containing the intensity foreground pixels is defined when an intensity foreground area corresponding to the intensity foreground pixels is greater than a predetermined intensity foreground area threshold, and saturation foreground pixels are obtained from all pixels in the fire-like image region based on saturation values thereof to obtain a saturation foreground area corresponding to the saturation foreground pixels. Linear regression analyses are performed on two-dimensional coordinates each formed by the intensity and saturation pixel areas associated with a corresponding image frame to generate a determination coefficient.

  • Publication number: 20060036168
    Abstract: An electrohydraulic shock wave-generating system for extracorporeal therapy of renal stones or musculoskeletal disorders includes a shock wave generator, a micro high-sensitivity camera, and a gap-controlling unit. The shock wave generator includes a truncated ellipsoidal bowl and two electrodes, each electrode having a portion inside the bowl, with a gap being defined between the electrodes. The micro high-sensitivity camera acquires an image of the electrodes for finding a size of the gap. The gap-controlling unit controls the size of the gap and moves at least one of the electrodes to adjust the size of the gap. A medical treatment for fragmenting stones or for curing musculoskeletal disorders can be carried out without increasing the operational voltage applied to the electrodes under gap control provided by the system. The system also includes a computer control unit to provide automatic control of the gap.
