Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] In view of the problems existing in the prior art, the recognition method of the stereoscopic video image format provided by the embodiment of the present invention is to use the image Fourier transform method to convert the stereoscopic video frame image to be recognized from the spatial domain to the frequency domain, that is, to obtain the stereoscopic video image format to be recognized. The Fourier magnitude spectrum of the stereoscopic video frame image, and by comparing the amplitude mean values ​​in the relevant regions in the Fourier magnitude spectrum, identify the format of the ste...

Abstract

The invention provides a stereoscopic video image format identifying method and system and a stereoscopic player, relating to the technical field of processing of stereoscopic video images. The method comprises the following steps of: receiving a stereoscopic video frame image to be identified, and converting the stereoscopic video frame image to be identified into a frequency domain from a space domain by virtue of Fourier transform, thereby obtaining a Fourier magnitude spectrum; and analyzing the size of a high-frequency component in the Fourier magnitude spectrum, and identifying the format of the stereoscopic video frame image to be identified according to an analysis result, thereby identifying the stereoscopic image format.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic video image processing, and in particular relates to a recognition method, system and stereoscopic player for stereoscopic video image formats. Background technique [0002] Stereoscopic display refers to the use of the parallax characteristics of the human eye to present a realistic three-dimensional image with spatial depth information under the naked eye condition of the human eye. Currently, common formats of stereoscopic video images include the following: [0003] 1. Frame sequential format (frame sequential): continuous alternate left-eye image and right-eye image; [0004] 2. Full-width left-right format (full-side-by-side): Compress the left frame image and the right frame image to half of the corresponding original resolution, and then synthesize a frame image. At the same time, in the compressed frame image, the left half frame The image is the left eye image, and the right field...
