Embodiment Construction

[0030] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, and to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The present invention provides a method for generating a novel high-robust video-based aesthetic QR (Quick Response) code. The generated video-based aesthetic QR code is called V-AQRCs, which is dynamic, machine-readable, and more attractive. Power, and can support more application scenarios. The overall process of the inventive method is as figure 1 with Figure 8 As shown, each implementation step is described below.

[0032] Step 1, using the context information of the continuous frames of the input video and the content features of a single frame, generate an adaptive standard aesthetic QR code sequence, that is...

Abstract

The invention provides a method for generating a novel high-robustness video aesthetic QR code, and relates to the technical field of digital image processing and computer vision. The method comprisesthe steps that an input video is cut and converted into continuous frame images, an aesthetic QR code is generated for each frame image, and an aesthetic QR code sequence corresponding to a video frame sequence is obtained; For the aesthetics QR code sequence, selecting a key frame by utilizing the structural similarity of aesthetics QR codes, and replacing a frame similar to the key frame in appearance with the key frame to obtain an optimized aesthetics QR code sequence; And for each optimized aesthetics QR code, using a robustness evaluation model to fuse the coding module and the video content, performing color conversion to obtain a robust color aesthetics QR code, and synthesizing all the robust color aesthetics QR codes into a video QR code. According to the method, a novel video AQRC is generated, and the method has dynamic and robust machine readability, is more attractive, and can support more application scenarios.

Description

technical field [0001] The invention relates to the fields of digital image processing technology and computer vision technology, in particular to a method for generating a novel high-robust video aesthetic QR code. Background technique [0002] With the popularity and development of smart devices and mobile payments, QR (Quick Response) codes have become one of the most used two-dimensional codes in the world. Traditional QR codes consist of visually unpleasant square black / white coding modules, which have triggered various aesthetic QR code (Aesthetic QR Code, hereinafter referred to as AQRC) work to improve the visual quality of QR code appearance, such as "Visualead "(N.Aliva, U.Peled, and F.Itamar., http: / / www.visualead.com / , 2012) developed a visual AQRC generator called Visualead, which retains the coding module and hybrid Raw contrast between images to synthesize aesthetic QR codes. However, the AQRC generated by Visualead has severe artifacts, especially the reduc...
