  • Publication number: 20200265591
    Abstract: The disclosure discloses a visual multi-object tracking based on multi-Bernoulli filter with YOLOv3 detection, belonging to the fields of machine vision and intelligent information processing. The disclosure introduces a YOLOv3 detection technology under a multiple Bernoulli filtering framework. Objects are described by using anti-interference convolution features, and detection results and tracking results are interactively fused to realize accurate estimation of video multi-object states with unknown and time-varying number. In a tracking process, matched detection boxes are combined with object tracks and object templates to determine new objects and re-recognize occluded objects in real time. Meanwhile, under the consideration of identity information of detected objects and estimated objects, identity recognition and track tracking of the objects are realized, so that the tracking accuracy of the occluded objects can be effectively improved, and track fragments are reduced.

  • Publication number: 20200237007
    Abstract: A voltage output circuit, an electronic device and an electronic cigarette are provided. The voltage output circuit includes a battery assembly and a control circuit. The battery assembly is electrically connected with an atomizing circuit. A first signal output end of the control circuit is connected with a main control circuit, and a second signal output end of the control circuit is connected with the main control circuit. When the main control circuit receives a sensing signal output by the first signal output end and a load working signal output by the second signal output end, the main control circuit controls the battery assembly to supply power to the atomizing circuit, such that the atomizing circuit starts to work, thereby solving the problem that the mechanical key is easy to be triggered by non-human in the related art to cause potential safety hazards.
