可信度函数 meaning in Chinese

belief function

Because the basic probability function could not be gotten analytically , a fuzzy system replaces it and the fuzzy rules ' consequent parameters are gotten by the least squares method based on sampling data
由于基本可信度函数不能解析获得，用一个模糊系统对其予以等价，模糊规则后件参数由样本数据通过最小二乘法获得。
A new rectangle box with a center gained by snake model in stead of the minimum bound box was pointed out , which not only benefits the calculation of factor sampling but also fits the real situation by which the real target is tracing ; further a measure based on the edge features of black - white image corresponded to the original image was given out , and the confidential function was given out as well ; a method is advanced to avoid of filter diffusion by using residual error prediction
提出了基于snake分割得到的目标轮廓及其形心确定的外包矩形盒来表示待跟踪目标，并在包围盒的对角顶点进行condensation采样。这种方法不仅有利于因子采样计算，也符合目标跟踪是以区域形心来跟踪的实际情况。提出用背景减除后的二值化图像中的目标包围盒作为condensation跟踪中的测度对比图，用预测包围盒同测度图之间的距离计算样本权值，并定义了可信度函数。
