Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0061] A kind of processing method of multi-viewpoint image that the present invention proposes, its flow process is as follows figure 1 As shown, the processing process is as follows: firstly, the color mapping relationship between the target image and the source image is established by using the histogram matching method; secondly, the watermark image to be embedded is embedded into the source image according to the gamma-corrected function representation, and the obtained The source image embedded with watermark; then, the target image and the source image embedded with watermark are encoded and transmitted by a multi-view video encoder, and the encoded target image and the encoded source image embedded with watermark are decoded at the user end , to obtain the decoded target image and the decoded source image embedded with watermark; final...

Abstract

The invention discloses a processing method of a multi-visual image. Firstly, building a color mapping relation of a source image and a target image by the adoption of a histogram matching method, and inserting a watermark image which is to be inserted into the source image according to gamma correction to obtain the source image inserted with watermark; carrying out coding transmission on the source image inserted with the watermark and the target image, and designing two methods which are color correction and copyright protection to process the source image inserted with the watermark after decoding. By the adoption of processing method, the accuracy of the color correction of the multi-visual image is guaranteed, simultaneously, the copyright protection of the multi-visual image can be effectively protected, and effectiveness of a multi-visual video system is improved.

Description

technical field [0001] The invention relates to an image processing method, in particular to a multi-viewpoint image processing method. Background technique [0002] In recent years, with the rapid development of network and information technology, digital multimedia information and works such as digital images, audio and video can be directly obtained and widely disseminated in digital form, and it is also very easy for pirates to copy or disseminate Digital multimedia information and works, resulting in the widespread copying and dissemination of copyright works without authorization, seriously infringing on the legitimate rights and interests of the original author. Therefore, effective copyright protection measures must be taken to prevent the illegal duplication and dissemination of digital multimedia information and works. Digital watermarking is an effective method to realize copyright protection. Invisibility, robustness, security and other characteristics are impor...
