IMAGE PROCESSING METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/192494

Kind Code:

A1

Abstract:

Disclosed are an image processing method and device. The method comprises: converting an original image into a low-pixel image according to a pre-set compression ratio; performing borderline detection on the low-pixel image to determine the borderline of a target image contained in the low-pixel image; and mapping the borderline contained in the low-pixel image into the original image to acquire the target image contained in the original image. By means of the technical solution of the present application, an original image is converted into a low-pixel image. Since the number of pixel points contained in the low-pixel image is relatively low, and a target image acquisition process is based on the low-pixel image, the target image acquisition process based on the low-pixel image shortens the duration for acquiring a target image, and increases the efficiency of target image acquisition.
