参考帧 meaning in English
reference frame
Examples
- One is achieved by not using the ac prediction for dct while intra coding , the other by encoding the all four modes of mb of b frame
二是对b帧的四种编码模式全部分配码位,有效地防止了p参考帧的差错对它的传播。 - Aimed at the problem that how to attain background frame in complex condition , a new method to acquire background was presented
摘要针对背景差分算法中在复杂背景下参考帧的提取问题，提出了一种新的运动目标检测方法。 - A set of consecutive digit time slots in which the position of each digit time slot can be identified by reference to a frame alignment signal
一组连续的数字时间片段，每一数字时间片段在组内的位置可参考帧同步信号来标识。 - The algorithm firstly puts current frame and reference frame throug h a low - pass filter to get low frequency sub - images with quarter pixels , then attains the best matched sub - block by full search , at last the area of reference frame covered by the sub - block are searched to get the best matched point
该算法首先将当前帧和参考帧通过低通滤波器得到数据量减为1 / 4的低频子图，然后用全搜索得到最佳匹配的低频子块，最后对低频子块所覆盖的原参考帧区域进行精细搜索得到最优点。 - The main contents of the study include such aspects as follows : ( 1 ) the moving vehicle auto - detecting grid arithmetic is studied and presented on the basis of the idea of the image difference arithmetic . the moving vehicle is detected whether or not to enter the field of view by calculating the grid dissimilarity between the current frame image and the reference frame image . dsdr ( dissimilarity descend rate ) is defined , and by calculating it the position of the moving vehicle in grids can be determined exactly , so the vehicle model image can be saved conveniently
本文所进行的研究主要包括以下方面： ( 1 )在图像差分算法基础上，研究提出了运动车辆自动检测的栅格算法，该方法通过计算当前帧与参考帧对应栅格的不相似度来检测是否有运动车辆进入视场；定义了不相似度下降率dsdr ，基于此，可以比较准确地确定出运动车辆在栅格中的位置，并可方便地将车辆图像作为模板保存下来。
