[6].PPT3在摄像头固定的情况下，背景差分法较为简单，且易于实现若背景已知，并能提供完整的特征数据，该方法能较准确地检测出运动目标但在实际的应用中，准确的背景模型很难建立如果背景模型如果没有很好地适应场景的变化，将大大影响目标检测结果的准确性像这副图中，背景模型没有及时更新，导致了检测的错误The basicprinciple ofbackground removalmethodisbuilding abackground model andproviding aclaification of the pixels intoeither foregroundor background[3-5].In acomplex anddynamicenvironment,it isdifficult tobuild arobust[raob st]backgroundAmodel.PPT4上述的帧间差分法和背景差分法都是基于灰度的基于灰度的算法在光照条件改变的情况下，性能会大大地降低，甚至失去作用The algorithmswe havediscued aboveare allbased ongrayscale.In practical applications especiallyoutdoor environment,the grayscales of eachpixel areunpredictably shiftybecause ofthe⑸为了解决光variations in the intensityand angleof illumination.PPT照改变带来的基于灰度的算法失效的问题，我们考虑用纹理特征来检测运动目标而算法是目前最常用的表征纹理特征的算法之一首先在图像中LBP提取相邻个像素点的灰度值然后对个像素中除中心像素以外的其他998个像素做二值化处理大于等于中心点像素的，标记为，小于的则标记为10最后将中心像素点周围的标记值按统一的顺序排列，得到值，图中计算LBP出的值为当某区域内所有像素的灰度都同时增大或减小一LBP10001111定的数值时，该区域内的值是不会改变的，这就是对灰度的平移不LBP LBP变特性它能够很好地解决灰度受光照影响的问题In orderto solvethe aboveproblems,we proposedanimproved LBP algorithm which isresistancetothevariations ofillumination.Local binarypatternLBPis widelyused inmachinevision applicationssuch asface detection,face recognitionandmoving objectdetection[9-11].LBP representsa relativelysimple yetpowerfultexture descriptorwhich candescribe therelationship ofapixel withits immediateneighborhood.The fundamentalof LBPoperatoris showed in Figl.The basicversion of LBP produces256texture patternsbased ona9pixels neighborhood.The neighboringpixelis setto1or0according tothe grayscalevalue ofthe pixelislarger thanthe value of centricpixel ornot.For example,in Figi7islarger than6so thepixel infirst rowfirst columnis settoZl.Arranging the8binary numbersin certainorder,we getan8bitsbinary number,which isthe LBP pattern weneed.For exampleinFig.l,the LBP is
