This face tracker enables the robust tracking of face with translation , rotation , zoom in / out , or partial occlusion 這個(gè)系統(tǒng)能魯棒地跟蹤人臉的平移、旋轉(zhuǎn)、縮放等運(yùn)動(dòng),并能魯棒地跟蹤小區(qū)域遮擋的運(yùn)動(dòng)人臉。
The implementation of this method exhibits robust results for different situation such as partial occlusion , rotation and shape distortion 目標(biāo)顏色模型的合理建立使得算法的粒子需求量少,計(jì)算復(fù)雜度降低,利于實(shí)現(xiàn)實(shí)時(shí)跟蹤。
Particle filter can deal those nonlinear and nongaussian estimation problems , and what ' s more , it does n ' t need the measurement equation which is hard to build in face tracking . experiments results demonstrate the algorithm is effective under complex situation such as changing background and partial occlusion 考慮到遮擋以及人運(yùn)動(dòng)的不確定性和非線性等因素,基于粒子濾波的跟蹤算法無需給出量測方程,且當(dāng)目標(biāo)發(fā)生遮擋時(shí)能夠自適應(yīng)的改變搜索空間,實(shí)驗(yàn)分析證明了該算法的有效性。
Compared to other shape matching algorithms , our shape modeling and detection algorithm has distinguishing features . our part - based and hierarchical strategy finds each part of the shape sequentially , rather than extracting all shapes from the image to match with the possible shape models . it can improve the accuracy and speed the detection processing , and can help to reduce or eliminate the effects of background clutters , partial occlusions and inner rotation in the object 形狀建模和檢測算法與一般方法相比,具有鮮明的特點(diǎn),即不需要先提取形狀再與可能的目標(biāo)模型匹配,而是采用分部分和分層次的處理思想,依次在圖像中搜索形狀的各個(gè)組成部分,由此提高了檢測的精度和效率,減小或消除了復(fù)雜背景、部分遮擋和目標(biāo)內(nèi)部組成部分旋轉(zhuǎn)的影響,同時(shí)可以實(shí)現(xiàn)并行處理。
