Abstract

The invention provides an image processing method and device. The method comprises the following steps: cutting out a first target image from a to-be-identified image; obtaining a target edge from the first target image and obtaining a second target image; extracting an outmost first target contour from the second target image and carrying out curve approximation of the first target contour to obtain a second target contour; and according to each point on the second target contour and a searched point found in the first target image in a normal line of each point on the second target contour, re-determining the position of each point on the second target contour. The invention provides the image processing method and device capable of improving the precision of extracted contours.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an image processing method and device. Background technique [0002] Image target contour extraction is an important technology in the field of computer vision. Although its history is not long, it has attracted widespread attention and research, and has been widely used in practice. In practical applications, people are usually only interested in some specific areas with obvious features in the image, these areas are called foreground or target, and the remaining areas are called background. Due to the influence of the background, in order to identify and analyze the targets, these targets need to be segmented from the image and their outlines extracted in order to better study and utilize the targets. Therefore, object contour extraction has a strong dependence on image segmentation algorithms. Image segmentation refers to dividing the image into several non-overlapping reg...
