To fulfill a TV guidance system task of fast recognizing and tracking missile target from sequential images including multiple interferences,a fast segmentation and target characteristic extraction algorithm of sequential images based on binary image index map was proposed.After the sequential images were processed to binary images,a Field Programmable Gate Array was used to scan the binary image once and an index map was built,and then Digital Signal Processing was used to scan the index map once.

针对电视制导系统需从包含多个干扰目标的序列图像中快速识别和跟踪导弹目标的要求，提出了一种基于二值图像索引图的序列图像快速分割及目标特征提取算法，在序列图像二值化后，只需由FPGA对其遍历一次就可得到一张含有目标信息的索引图表，再由DSP对该索引图表边遍历边计算就可得到图像所含目标的数量、面积、质心坐标、二阶矩不变量等特征。

A sequenced method in consideration of the sample range was proposed to rationally array classifiers of a support vector machine with binary tree architecture. A sample distribution radius and a sample distribution distance were introduced to estimate sample range of all classes in high-dimension characteristic space. The classes with bigger sample range were classified earlier in the higher nodal point of the binary tree architecture, and were given wider classificatory areas in the characteristic space.

考虑到样本的分布情况对分类器推广能力具有较大影响，提出一种次序二叉树支持向量机多类算法，采用样本分布半径和样本分布距离估算各个类别的样本在高维特征空间中的分布情况，把分布半径较大的类别或者分布距离较大的类别较早地分出来，并且在特征空间中给其划分较大的分类区域。

Biometrics is a kind of science and technology using individual physiological or behavioral characteristics to verify identity.

生物特征识别是利用人类特有的生理或行为特征来识别个人身份的技术，它提供了一种高可靠性、高稳定性的身份鉴别途径。

The Bloodhound possesses, in a most marked degree, every point and characteristic of those dogs which hunt together by scent.

寻血犬拥有大量显著的特征，这些特征都指出，他是一种典型的以嗅觉捕猎的狗。

Aimed at the characteristic of retinal images, the algorithm of extraction of branch point and crossing point of vessels is proposed, the content includes the confirmation of the number of branch points and the precise extraction of the location of branch points. Branch point corresponding is determined by distance and the angles.

针对视网膜图像的特点，提出了一种血管分支点和交叉点的提取方法，包括分支个数的确定、分支点位置的精确提取等；在特征点对应性确定方面，提出利用距离度量和具有旋转、平移不变化的角度特征进行对应性的确定。
