Abstract: The present application discloses a system and a method for determining cable operational quality based on an environment where a cable is located. The method includes: acquiring collected data of individual cable environment parameters within a preset time period and a plurality of associated cable operational quality influencing factors of individual cables, and determining cable environment parameter influencing values of the individual cable operational quality influencing factors correspondingly based on the collected data of the individual cable environmental parameters; in the presence of a plurality of cable environment parameter influencing values for each of the cable operational quality influencing factors, determining a final analysis value for the cable operational quality influencing factor based on the individual cable environment parameter influencing values of the cable operational quality influencing factor and pre-stored attributes of each associated individual cable environment parameter.

Abstract: A target element generation method and apparatus, an electronic device, and a storage medium are provided. The method includes: displaying an editing page on which a stylized image is displayed, where the stylized image is an image generated by performing target style conversion on an initial image; and displaying, in a target region of the stylized image, a target element corresponding to a processing operation for the target region in response to the processing operation for the target region, where the target element is an element generated by re-drawing the target region based on an initial element corresponding to the processing operation.
