- When we ' ve converted you to a proper point of view we may quit , but not before
哪天我們把你的想法改得對(duì)頭了，我們就離開，否則不走。 - 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
本方案的實(shí)現(xiàn)過(guò)程為：分割部分：對(duì)運(yùn)動(dòng)目標(biāo)的前后三幀進(jìn)行兩次塊匹配運(yùn)動(dòng)檢測(cè)，通過(guò)找出兩個(gè)匹配結(jié)果中運(yùn)動(dòng)圖像塊的公共部分，獲得組成運(yùn)動(dòng)目標(biāo)的圖像塊；求出運(yùn)動(dòng)目標(biāo)圖像塊的形心作為運(yùn)動(dòng)目標(biāo)的中心，以此中心為端點(diǎn)，向四周發(fā)散出角度間隔為的n條射線，射線的另一端終止于圖像的邊緣；在每條射線上按照一定的準(zhǔn)則(點(diǎn)的梯度和與目標(biāo)中心的距離在一定閾值范圍內(nèi))找出n個(gè)初始輪廓點(diǎn)；以這些初始輪廓點(diǎn)作為主動(dòng)輪廓模型( snake )的初始點(diǎn)，用改進(jìn)的貪婪算法使snake收斂到待分割的運(yùn)動(dòng)目標(biāo)輪廓上。 - It's difficult to find proper point in a sentence. 用proper point造句挺難的
