The box-counting dimension of a non-stellate neuron changes continuously with its rotation. During preprocessing for box-counting, non-stellate neurons should be arranged so that the major diameters of their dendrite fields are parallel. A non-stellate neuronal picture should have the smallest fractal dimension when the angle between the horizontal axis and its major diameter is about 45°. The box-counting method does not consider the position of a picture on the computer screen. Therefore a dispersion of the box dimension values of a neuronal sample is rather large and their mean value is with larger variance. Modified box-counting method partly diminishes these findings. To improve a dependence of neuronal rotation on the box-counting dimension of non-stellate neurons, prior to applying box-counting method, non-stellate neurons should be arranged so that the major diameters of their dendrite fields are parallel.
非星状神经元的计盒维数随其旋转而连续变化。在计盒预处理过程中，应排列非星状神经元，使其树突场的长轴平行。当水平轴与其长轴之间的夹角约为45°时，非星状神经元图像的分形维数应最小。计盒法不考虑图像在计算机屏幕上的位置。因此，神经元样本的盒维数值分散性相当大，其平均值的方差也较大。改进的计盒法部分减少了这些结果。为了改善神经元旋转对非星状神经元计盒维数的依赖性，在应用计盒法之前，应排列非星状神经元，使其树突场的长轴平行。
