To this end, the ultrasound cardiograph is filtered and fuzzily boundary enhanced, a threshold is set to obtain a binary image, then the heart's boundary is got through ellipse curve fitting, cubic spline interpretation and smoothing.

首先对超声心动图像进行滤波以消除图像中的噪声，并运用模糊数学理论进行模糊边缘增强，提取超声心动图像的内外膜边缘信息；接著对超声心动图像作二值化处理和椭圆曲线拟合，初步得到心脏的内外膜边缘；再采用相应的三次样条插值和平滑技术，得到光滑、连续的心脏内外膜边缘。

We present k -Degree T-Bezier basis function and reparametrize it on the interval [0,1],representation of ellipse and cardioid and G~1 condition of T-Bezier curves based on the analysisof T-Bezier basis function and terminal properties. The results have definite geometric meanings that are useful for surface modeling.(3) We presents G~1 of C-B-spline curves and C-Bezier curves.

3给出了C-曲线间的G~1拼接条件，利用C-Bézier曲线能够精确表示半圆弧和半椭圆弧的性质，在实际应用过程中需要精确表示半圆弧和半椭圆弧的地方利用C-Bézier曲线来代替C-B样条曲线，从而较好的解决了在C-B样条造型系统中无法精确表示圆弧的问题。
