In theory, every problem of involving morphological analysis and examination can be solved with digital image processing technology. Because there are irregular form structures, uncertain space positions and impure samples of the human helminth eggs, digital application and research is underdeveloped in parasitology. The recognition and analysis of human helminth eggs is unable to be performed by means of automatic instrument as blood cell. As a result, they have been observed and distinguished under the microscope through the naked eye for a long time.

从理论上说，凡是牵涉到形态分析和检测的问题都可以用数字图像处理技术来解决，但由于人体寄生虫虫卵的不规则的形态结构、空间方位和标本杂质较多等原因，数字图像技术在寄生虫学上的应用和研究很少，寄生虫虫卵的识别无法象血细胞分析一样用自动化仪器进行，长期以来只能依赖人眼在显微镜下进行观察分辨。

Structures of cochlea were measured on the images of position I and II ,including upper hemicycile width of Basal turn, lower hemicycle width of Middle turn, Middle turn height, Cochlea height, Modiolus area, length and width of Cochlea Nerve Canal on image I and Basal turn diameter, Basal turn lumen on image II.

在标准方位图像上设计并测量耳蜗9个结构径线(笔者分别定义为径线A—I，图Ⅰ A-G，图Ⅱ H-I)，径线A约衡量底周上半周宽度，径线B约衡量中周下半周宽度，径线C约衡量中周高度，径线D约衡量耳蜗高度，径线E约衡量蜗轴面积，径线F衡量蜗神经管宽度，径线G衡量蜗神经管长度，径线H约衡量耳蜗底周外径，径线I约衡量底周管径。

The using of the technologies of DOA in the orientation estimating of interference is discussed, then an evolutive ESPRIT algorithm is put forward which avoids the eigendecomposition and is easily achieved. To the MUSIC algorithm, an easy eigendecomposition algorithm for Hermitian matrix is presented. It breaks away form the complex matrix decomposition such as QR algorithm. Basing on the whole matrix, the algorithm makes use of the multiplication operation of matrix and vector, which attains simpleness and is fit for DSP. In the field of DOA estimating of correlation interferences, spatial smoothing algorithm consumes too many array units.

讨论了DOA技术在干扰源方位估计中的应用，提出了一种ESPRIT演变算法，该算法避开了特征值分解，实现简便；在MUSIC算法的实现中提出了一个Hermitian矩阵特征值分解算法，该算法摆脱了复杂矩阵分解，从矩阵整体出发，主要的运算是矩阵与矢量的乘运算，算法简单，非常适合DSP芯片实现；在相关源的DOA估计中，空间平滑技术使阵元的损失非常大，本文提出了一种进一步降低阵元消耗的平滑技术—随机空间增益法，其在运算量上的增加很小，但对于相干源的去相关确是有效的。
