中文摘要:
      图像显示的质量在信息技术和模式识别应用中起到举足轻重的作用,而图像显示时候的串扰,是影响图像显示质量的一个重要的因素,因此分析和研究图像显示中的串扰现象将有助于图像显示技术的改进。本文在充分研究立体显示中串扰形成原因的基础上,提出了一种基于图像灰阶查找表算法的消除串扰方法。该方法从受试者的观看角度来看,使用灰阶查找表来测量每个左右图像,并用新的灰度组合替换原有的左右图像,从而补偿由于左右眼图像分离不彻底造成的亮度影响,最终使左右眼图像的亮度更接近理想状态,而不会出现串扰。研究结果表明:该方法的平均串扰抑制率可达70%,立体图像的亮度也提高了13%左右。同时,本文还对实际立体图像进行了屏幕测试,结果表明该方法对消除串扰效果显著。
英文摘要:
      The quality of image display plays an important role in the application of information technology and pattern recognition. The crosstalk in image display is an important factor affecting the quality of image display. Therefore, the analysis and research of crosstalk in image display will help to improve the image display technology. Based on the study of the formation mechanism of crosstalk in stereoscopic display, this passage proposes a crosstalk cancellation method based on lookup table algorithm. From the perspective of the viewer, each left and right image is replaced by a new gray-scale combination to compensate for the brightness impact caused by incomplete separation of left and right eye images. Finally, the brightness distribution of each channel is infinitely close to the ideal state without crosstalk. The results show that the average crosstalk rejection rate of this method can reach 70%. Besides, the brightness of the stereoscopic image is increased by about 13%. At the same time, the screen test is carried out in the light of the actual stereoscopic image, and the crosstalk cancellation effect is obvious.
