背景对比度 meaning in English
background contrast
Examples
- Due to dynamic complex background and defects of infrared image , which are low contrast between object and background , blurred edge of object and high amount of noise , objects detection and tracking is very difficult in this case
由于动态复杂背景,加上红外图像普遍存在目标与背景对比度低、目标边缘模糊和噪声大等问题,给目标的检测与跟踪带来很大的挑战性,目前国内外相关文献还很少。 - All of above make the miss distance of the missile difficult to estimate in shooting range . in order to solve these problems , a novel method for detecting and tracking small moving point target in image sequence is proposed in this paper , based on combination of the correlation of multi - frames and wave gate techniques . especially , the qualifications to confirm the target and the establishment of the wave gate based on size and characteristic moving parameters of the target are stressed in the paper
针对目前靶场所面临的测量目标小、距离远、目标与背景对比度小,不具有形状信息的实际问题,提出了一种基于多帧相关技术与波门选通技术相结合的快速目标识别与跟踪方法,特别探讨了多帧相关技术中目标确定的理论判据,并综合考虑目标的尺寸因素和目标的运动特征研究了一种新的波门设定方案。 - At present , the practical problem that the target place faces is that the target is too small , the distance is far , the contrast ratio between the target and background is small . in order to improving the recognition capability of the equipment to the low contrast ratio target , fast and effective pattern recognition becomes one of key technology which influences systematic function
目前靶场所面临的实际问题是测量目标小，距离远，目标与背景对比度小，为了提高靶场光测设备对低对比度目标的识别能力，快速、有效的图像识别处理成为影响系统性能的关键技术之一。
