用Lindeberg的尺度空间理论以获取目标尺度信息。但现有算法中将尺度由2.D矢量压缩为1一D量,未能精细地
刻画目标仿射变换时的尺度变化,从而限制了算法的适用范围。为此,该文将尺度维1.D滤波推广至2一D,构造得

目标的有效跟踪,提高了算法在目标尺度变化时的自适应性,并扩大了算法的适用范围。
关键(Scale adaptive mechanism in the target tracking algorithm based on Mean-Shift algorithm is an important direction of research. A typical method using Lindeberg' s scale space theory to obtain the target scale. However, the existing algorithms will scale from 2. D vector compression for 1-D volume, not fine to portray the target affine transformation of scale changes, thus limiting the scope of application of the algorithm. To this end, the paper will scale dimension. D filter to the 2-D structure has been the vertical D scale space and the use of narrow inter-dimension and scale dimension of the Mean-Shift alternating iteration, effective tracking of the target position in space and scale direction to improve the self-adaptive algorithm when the target scale changes, and to expand the scope of application of the algorithm.
