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. Whether a flame image exists in the image frames is determined based on the determination coefficient and a predetermined identification threshold.

Abstract:
An antenna structure includes an antenna pattern having a feeding hollow and a grounding hollow formed in one surface thereof and a feeing cable having an inner lead, a metallic shield, a feeding piece connected to one end of the inner lead and a grounding piece connected to one end of the metallic shield. The feeding piece and the grounding piece of the feeding cable respectively connect to the antenna pattern by conductive glue prearranged in the feeding hollow and the grounding hollow of the antenna pattern. Therefore, the electrical connection between the antenna pattern and the feeding cable is more stable. In addition, the antenna pattern can be formed integrated with a housing of an electric apparatus or plated on the housing, so an extra space can be saved to make the electric apparatus more compact. The present invention also discloses a method for manufacturing the antenna structure.
