  • Patent number: 12380567
    Abstract: The present disclosure provides an image processing method and apparatus, and relates to the field of image processing, and in particular to the field of image annotation. An implementation is: obtaining an image to be processed including a target region to be annotated; in response to a first click on the target region, performing a first operation to expand a predicted region for the target region based on a click position of the first click; in response to a second click in a position where the predicted region exceeds the target region, performing a second operation to reduce the predicted region based on a click position of the second click; and in response to determining that a difference between the predicted region and the target region meets a preset condition, obtaining an outline of the predicted region to annotate the target region.

  • Patent number: 8455643
    Abstract: A white-light organic electroluminescent material based on 8-hydroxyquinoline and the method for preparing the same, as well as an organic light emitting diode including this material. The material may be the compound represented by the Formula (IX) having a DCDC group, a 5-position substituted 8-hydroxyquinolinyl group and a carbazolyl group as red light-, green light- and blue-light emitting groups, respectively. It exhibits a spectrum having a band width of 182.4 nm that substantially covers the visible-light region, and has a color coordinate of (0.3177, 0.3946), which just locates within the white-light area. Such a material is capable of realizing a white-light emission, and may be used in a white-light OLED as a single light-emitting layer, which can decrease the number of layers of the white-light OLED and thereby improve the luminous efficiency, stabilize the light color, lower the turn-on voltage and simplify the fabrication process.
