In china , after the initial orientation , the eye bounces around the total area of the listing consideration set 在中國,除了熱點都源自左上方外,人們在整個的頁面上跳來跳去的尋找信息。
The settling behaviors of the rectangular particle were affected significantly by the initial orientation angle and length - width ratio 粒子的初始取向角和長寬比對其沉降過程有較大影響。
The settling behaviors of a rectangular particle with different initial orientation angles and length - width ratios were simulated by using distributed lagrange multiplier / fictitious domain method 摘要為了對方形粒子在二維垂直通道中的沉降運動特性進行研究,應(yīng)用了拉格朗日乘子虛擬區(qū)域方法對不同初始取向角、不同長寬比情況下方形粒子的沉降運動進行了直接數(shù)值模擬。
With the increasing initial orientation angle and length - width ratio , the drifting distance , the fluctuation of the orientation angle , lateral drifting velocity and rotation velocity all increase , while the final settling velocity decreases with the increasing length - width ratio 初始取向角和長寬比增大,則粒子的橫向漂移以及取向角、側(cè)向漂移速度和轉(zhuǎn)動角速度的振蕩幅度都增大;同時隨著長寬比的增大,粒子的沉降速度相應(yīng)減小。
This paper presents a new face detection algorithm for color video images based on skin color and multimodal information fusion . first , this paper presents a new means for selecting skin samples ; and then comparing skin distribution in the eight color spaces and analyzing the adaptability for different skin patterns , poses a face initial orientation ' s method which uses the single gaussian model in the tsl color spaces , and calculates skin probability images ; afterwards comprehensive comparing three typical threshold value separating algorithms , put forwards a face separating method which bases on region growing and fuses multimodal informations ; final , raises a face confirming algorithm which fuses three shape features 首先提出了?種新的膚色樣本選取方法;然后通過對八種色空間膚色分布的比較以及不同膚色模型適應(yīng)性的分析,提出了在tsl色空間上用單峰高斯模型模擬膚色分布,求得膚色概率圖進行人臉初定位的方法;隨后在綜合比較三個典型閾值化分割算法的基礎(chǔ)上,提出了融合多源信息進行區(qū)域生長分割人臉的算法;最后提出了融合三個形狀特征的人臉確認(rèn)算法。
