由于天文底片很多时候都见不到每幅的间格，因此最好利用第一格拍摄日间景色或用闪灯拍摄任何景物，以定格位。 | | 3. | However , most of the current wireless networks still work in low bandwidths , and mobile devices still suffer from weak computational power , short battery lifetime and limited display capability . therefore , this thesis deals with developing a very low bit - rate bi - level video coding technique , which can be used in video communications almost anywhere , anytime on any device as follows : ( 1 ) convert true color video sequences from ccd and video card to grayscale ones , ( 2 ) detect static region of successive frames by the sum of absolute differences ( sad ) and update current frame using static region of previous frame , to decrease flicker . ( 3 ) threshold the images to bi - level video sequences using ridler ' s iterative selection
为此，本论文在传统h . 26x和mpeg - x等视频编解码技术的基础上提出了一种新的基于轮廓的视频编解码方案，步骤如下： ( 1 )先把从ccd摄像头捕捉到的视频帧序列转换成灰度帧序列， ( 2 )在灰度帧序列的基础上通过sad算法找出相邻帧的静态区域，用前一帧的静态区域更新当前帧的相应区域，这样可以降低画面闪烁， ( 3 )然后用灰度直方图迭代所产生的阈值二值化图像，生成基于轮廓的视频帧序列， ( 4 )最后运用基于上下文的算术编码技术对由第三步生成的二值化视频帧序列进行算术编码。 | | 4. | A good overall match is obtained in a few iterations . because the difference between moving object in successive frames is unobvious in color video sequences , the last position of locating in the former frame just turns into the initial position of the latter frame which solves the problem of determination of initial position
由于在彩色视频序列中,相继两帧之间运动物体的差异很小,因此将主动形状模型对前一帧图像目标定位的结果作为后一帧图像目标定位的初始位置,解决了主动形状模型难以确定初始位置的问题。 | | 5. | Following are detailed steps of this system : in the segmentation section , we use three successive frames to detect the motion infomation of the pictures , by using blockmatching algorithm in two successive frames twice , we can get two pictures composed of motion blocks of the moving object , then we find out the common motion blocks of the two pictures , experiments prove these blocks approximately compose the moving object . after getting the motion blocks , we calculate the center of these blocks as the center of the moving object , thus we can use the center point as the origin , construct n straight linesjoining the boundry of the image and the center . on each line , we can find out a proper point near the object contour according to some criteria , then we use these n points as the initial points of the snake and let the snake converge on the object contour , thus finish the segmentation of the moving object
本方案的实现过程为：分割部分：对运动目标的前后三帧进行两次块匹配运动检测，通过找出两个匹配结果中运动图像块的公共部分，获得组成运动目标的图像块；求出运动目标图像块的形心作为运动目标的中心，以此中心为端点，向四周发散出角度间隔为的n条射线，射线的另一端终止于图像的边缘；在每条射线上按照一定的准则(点的梯度和与目标中心的距离在一定阈值范围内)找出n个初始轮廓点；以这些初始轮廓点作为主动轮廓模型( snake )的初始点，用改进的贪婪算法使snake收敛到待分割的运动目标轮廓上。 | | 6. | In the section of temporal segmentation , construct the stationary panoramic background first . we need get every frame of the shot at first , and get the motion vectors of every frame , and calculate the motion parameters . use the motion parameters , we can get the transformation of successive frames , and then get transformation of every two frames
当获得了背景的全景图后,就可以用经过校准的各帧图像和背景相关部分进行差分运算,则该帧图像中背景部分相减后为零,运动目标部分非零,从而得到非零区域就获得了该帧中运动目标所在的区域。 |
