Research On Stereo Image Cloning And Crosstalk On The Stereoscopic Display

Stereoscopic displays rapidly growing recently have attracted much attention due to providing viewers with stereo environments like the real world around us. Research on stereoscopic image cloning is becoming more and more popular. Crosstalk is often a primary factor degrading stereo image quality in a stereoscopic display. Threrfore, it is significance to study the stereoscopic image cloning and crosstalk in stereoscopic displays.This paper carries out research on stereoscopic image cloning and crosstalk reduction. The main work of this paper includes the following aspects.In stereo image cloning, the scale of the source image need be adjusted due to the depth information. When the stereo images are captured by different cameras, the scale of object in stereo image is related to the disparity and baseline distance between two cameras. Image recognition technologies are used to identify the parameters of objects. The relationship between different stereo images is built up throuth the objects, which can be ued to guide the scaling adjustment of the source image in the target image.Crosstalk is often a critical and primary factor causing eye fatigue and degrading stereo image quality in a stereoscopic display. The optical model of parallax barrier and lenticular lens stereoscopic display is developed based on the principle of light transmitted. The optical model is used to analyze the factors affecting the crosstalk. To reduce the crosstalk, the polarized parallax barrier autostereoscopic display is proposed. The simulation shows crosstalk is eliminated in the autostereoscopis display based on polarized parallax barrier. The autostereoscopic display based on polarized lenticular lens can produce high quality stereoscopic images without crosstalk at the optimal viewing distance. To reduce the large and heavy lenticular lens, a blazed gating is proposed.A viewer wearing stereo glasses sees a 3D image; but a viewer not wearing these sees both images superimposed, causing a ghosted double contours image in a stereoscopic display. Viewer crosstalk is reduced by minimizing the saliency-weighted crosstalk visibility index map by reducing the intensity of leakage, compressing the disparity, and using local intensity mapping method. Experimental results show that the 3D+2D image can provide a strong 3D depth impression for viewers wearing glasses and a high-quality 2D image for viewers not wearing glasses on stereoscopic displays.
