Methods and systems to adaptively detect object borders from electronic device images

摘要

A method of automatically identifying a border in a captured image may include capturing an image of a target by an image sensor of an electronic device, and, by one or more processors, processing the image to automatically detect a border of the target in the image by applying an automatic border detection method to the image. The method may include presenting the image of the target to a user via a display of the electronic device so that the presented image comprises a visual depiction of the detected border, receiving an adjustment of the border from the user, determining whether to update the default parameters based on the received adjustment, in response to determining to update the default parameters, determining one or more updated parameters for the automatic border detection method that are based on, at least in part, the received adjustment, and saving the updated parameters.

1. A method of automatically identifying a border in a captured image, the method comprising:
by an image sensor of a mobile electronic device, capturing an image of a target; by one or more processors:
processing the image to automatically detect a border of the target in the image by applying an automatic border detection method to the image, wherein the automatic border detection method uses one or more default parameters,presenting the image of the target to a user via a display of the mobile electronic device so that the presented image comprises a visual depiction of the detected border,receiving, via a user interface, an adjustment of the border from the user,determining whether to update the default parameters based on the received adjustment by:
determining a difference between one or more border coordinates associated with the received adjustment and one or more border coordinates associated with the default parameters, andin response to the difference exceeding a threshold value:
determining one or more updated parameters that minimize the difference, andreplacing the default parameters with the updated parameters, andsaving the updated parameters.
