Embodiment Construction

[0043] see figure 1 , an automatic painting and calligraphy frame matching method based on edge detection and image stitching, realized through software programming, specifically, based on the cross-platform computer vision library OpenCV, which can run on operating systems such as Linux, Windows and Mac OS. Including the following steps:

[0044] Step 1, read the input frame image and portrait image to be processed.

[0045] Specifically, use the modal dialog box to obtain the relative address of the incoming image. The image types that can be used include images in .jpg, .png and other formats, and store them in the data structure of IplImage as pImgSrc and pyuantu, respectively Indicates the loaded frame image and portrait image.

[0046] Step 2, using the canny algorithm to perform edge detection on the picture frame image to obtain an edge information image.

[0047] Specifically, the following steps are included:

[0048] (1) Use the cvCvtColor function to convert th...

Abstract

The invention proposes a painting automatic enframing method based on edge detection and image splicing, and the method comprises the steps: reading a painting frame image and a portrayal image through a modal dialog box; carrying out the grey scale transformation of the painting frame image, and carrying out the edge detection of the image through a canny algorithm; calculating the size of a connection region, and screening out the peripheral contour of the painting frame image; trimming the painting frame image according to the peripheral contour; extracting the feature point parameters of the painting frame image according to the peripheral contour; carrying out the splicing of the painting frame image through setting an area of interest; carrying out the splicing of the painting frame image and the portrayal image through the setting of the area of interest of the image, finally outputting a preview image, and carrying out the storage of an output image through the modal dialog box. The method is convenient for use, can recognize a digital picture, can achieve the batch production, and solves a problem of low efficiency, caused by the manual making of a painting image through other image processing software, to some extent.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an automatic frame matching method for calligraphy and painting based on edge detection and image splicing. Background technique [0002] For calligraphy and painting sellers, it is necessary to configure multiple frames for a painting to meet the needs of different customers. Moreover, the picture frame image material obtained by the merchant is generally a triangular frame. In the traditional mode, merchants use image processing technology to complete the triangular frame into a four-cornered circular frame, and then stitch and match it with the oil painting. This kind of manual action has become a pain point in the industry that hinders the sales of oil paintings in the case of large-scale oil painting sales. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and propose a method for automati...
