Abstract

The invention provides an apparatus and method for extracting a boundary of an object in an image and an electronic device, so as to at least overcome the problem of low extracting accuracy or needing multiple manual adjustments in the existing boundary extracting technologies. The apparatus includes: a position determining unit, configured to determine a start point and an end point of a boundary of an object in an image and to determine a position of a reference point relevant to the start point and the end point; a first direction determining unit, configured to determine a first direction of the boundary; a gradient map obtaining unit, configured to obtain a gradient map of a first region; a gradient attenuating unit, configured to attenuate in the gradient map the gradients of a second region; and an extracting unit, configured to extract a boundary of an object. The method is configured to perform the processing which can achieve the function of the apparatus. The electronic device includes the apparatus. The technology of the invention can improve the accuracy of boundary extracting, and can be applied in the field of image processing.
