Abstract

The present invention provides an image processing method and an image processing device. The image processing method comprises the steps of: generating a first mask contour line of a processed image according to the color of the processed image; extending pixels in the first mask contour line, so as to determine a contour ribbon area; generating a second mask contour line of the processed image in the contour ribbon area according to colors of pixels of the contour ribbon area; generating blanking colors for pixels in an area surrounded by the second mask contour line of the processed image according to colors and positions of pixels on the second mask contour line of the processed image; and carrying out image processing on the processed image according to the blanking colors for the pixels in the area surrounded by the second mask contour line. The present invention further provides the image processing device. According to the image processing method and the image processing device disclosed by the present invention, signs and characters in the image can be subjected to blanking processing excellently.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] Images often contain some sensitive icons and texts. How to eliminate such sensitive information in images and make the processed images look unmodified has always been a concern in the field of image processing. [0003] The traditional approach to this problem is known as mosaicing. This method is simple and efficient, and can effectively hide information, but the traces of modification are obvious, and in some cases it will arouse the curiosity of the viewer. In recent years, automatic image completion has become a research hotspot in the fields of computer vision and computer graphics. [0004] Image auto-completion can fill the area to be completed with the content of other parts of the image without defects, especially the area with obvious texture features can obtain a good completion effect. The famous...
