  • IMAGE DETECTION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
    Publication number: 20230245441
    Abstract: The technology of this application relates to an artificial intelligence terminal-based image detection method and apparatus, and an electronic device. The method includes obtaining a to-be-detected image, determining a light source region of the to-be-detected image and a foreground region of the to-be-detected image, and determining a blurring degree of the to-be-detected image based on the light source region and the foreground region. Impact of a light source on clarity of the to-be-detected image is determined by performing light source region detection and foreground region detection on the to-be-detected image, to effectively detect whether an image shot in a backlight condition is blurred.
    Type: Application

  • Green laser system
    Patent number: 8675698
    Abstract: A green laser is made by constructing a laser cavity that includes within it a laser diode, a non-linear crystal such as KTP, and a lens. The boundaries of the cavity are not defined by the ends of the diode itself, but are instead defined by the ends of an apparatus that includes the lens and the KTP or similar crystal.
