An image processing method and apparatus, where the method includes determining m boundary points of a target image, acquiring a color component of a non-boundary point in a jarea, where the jarea is a neighborhood of the jboundary point in the m boundary points, 1&#x2266;j&#x2266;m, and m is a positive integer greater than or equal to 1, and performing synthesis processing according to the color component of the non-boundary point in the jarea, to obtain a color component of the jboundary point, and by means of processing on a boundary point of a target image, precision of image matting and synthesis processing may be improved, and may be applied to a real-time image matting and synthesis process.

Image processing method and apparatus

The present invention discloses a method and an apparatus for detecting a convex polygon image block, and a device. The method includes: acquiring an image collected by an image sensor; acquiring a corner set, where the corner set includes a corner in the image, and the corner is an intersection point at which any two straight line sides that are not parallel to each other in the image intersect; and detecting a convex polygon image block in the image according to the corner set, where a shape of the convex polygon image block is a preset shape and a similarity between the convex polygon image block and a preset image block exceeds a preset first threshold. The apparatus includes: a first acquiring module, a second acquiring module, and a detecting module. In the present invention, the convex polygon image block can be detected from the image.
