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。
