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。

Results Spatial relations of the tumors to the lamina terminalis, anterior commissure and anterior communicating artery complex were clearly shown in T2R images. The optic nerves, optic chiasm and optic tracts were detected in 93.3%, 100% and 86.7% of the patients on T2R images and 66.7%, 93.3% and 66.7% on T1 weighted images, respectively. Detection rate of optic pathway on T2R images was higher than that on T1 weighted images.

Along with the development of the information technology, it is demanded to storage, record and transmit kinds of static images and"concretionary"images largely, such as the files, authentic works, images, nephograms and remote sensing images.

现代通信业务的发展，需要大量地存储、记录和传输文件、真迹、图形、气象云图、遥感图像等各类静止图像和"凝固"图像。

When audience face these images, it is natural to invoke the memory of source images, and it is such basic memory or source images intention that produce the reaction and confrontation to Xus works, spur his works to enter audiences habitual recognition of images, and combine thinking with image cognition to form new interpretation of images, as to highlight the dubiety of source images and to increase the possible reinterpretation of source images, but the artists conceptual interference is not close-ended but discloses the mechanism of contemporary image reading: i.e. the interaction between image and audience, as result such works are the presence of artistic conception but the absence of artist and that artist doesnt stress the input of personal experience into the work, but looks for the methodology of image-construction and the combination of thinking methods for creating the entity of joint between image and language.

当观众面对这些图像时，很自然地唤起对原有图像的记忆，正是这种基本记忆或原图像意图的捕捉对许昌昌的作品产生了反作用和对抗，促使作品图像进入到观众的图像识别习惯中，将思考与图像认知结合，形成新的图像阐释，既是突出原图像的可疑性，又增加了对原图像的重新解释的可能性，但艺术家的观念介入并不是封闭的，而是敞开了当代图像阅读的机制：即图像与观众的互动性，这样的作品是艺术观念在场而艺术家缺席，艺术家不强调个人生活经验进入作品，而是寻求图像构成的方法论和思维方法论的结合，创造图像与语言切合的实体。

By TM images the linear structures, water system, the outer edge of Tianchi Volcano trachite are extracted. By the sensitivity of SAR images to geomorphology, the distribution of parasitical volcano cone and lava fornix around Tianchi volcano are interpreted. With the aerial photos the parasitical lava of Qixiangzhan, Baiyun and Bingchang stage are filtered. At the same time by orthogonal cross-course wavelet transform, texture analysis is carried on to ERS-2 SAR images, and the texture characters are filtered. On the basis of the spectrum character of multi-band of TM images, multi-band algebraic grouping is made, and the factor of texture character factor and band grouping of TM images are input to BP neural network classification model. The good classified results are received.

ABSTRACT Objective To discuss the importance of the study of conformation and variation of extrahepatic bile duct before gallbladder operationMethods The images of 100 cases having normal structure of gallbladder and extrahepatic bile duct were studied;the conformations and confluence sites were analyzedResults Among the 100 cases,97 cases had clear images of extrahepatic bile duct (97%),3 cases with large amount of air bulbs in bile duct because of the laxation of the lower common bile duct still had clear images of the general conformation of extrahepatic bile duct,87 cases had clear images of gallbladder and cystic duct (87%),13 cases (13%) had partial images of gallbladder or cystic ductConclusions ERCP can clearly show out the conformation and variation of extrahepatic bile duct and cystic duct and it is of important value before gallbladder operation

目的 通过对100例胆囊及肝外胆管正常结构尚存在的患者ERCP图像资料进行归纳和分析，探讨胆囊手术术前了解肝外胆道系统形态及变异的重要性。方法选出100例胆囊及肝外胆管正常结构尚存在的患者图像，对其形态、汇合位置进行分析。结果 100例患者图像中肝外胆管显示清晰者97例(97%)，3例因胆总管下端开口松弛导致大量气泡进入胆道，但肝外胆管大体形态显示尚清晰，胆囊及胆囊管显示清晰者87例(87%)，13例(13%)仅部分显示胆囊或胆囊管。结论 ERCP可以清晰显示肝外胆管及胆囊管的形态及变异情况，对于胆囊手术术前了解肝外胆道系统形态及变异有重要价值。 ERCP；胆囊管；肝外胆管

We experimentally evaluate the effect of the proposed method using our emotion retrieval algorithm and random algorithm. Four kinds of emotion images, thick fashion images, succinct fashion images, passional scenery images and wide view scenery images are retrieved and compared. The experimental results show that our retrieval algorithm is better than random algorithm.

There were high density images shaped as rope and slip in lungs of model control group rats and the pleura near the images were a little thickening. In MTX treated group, there were high density images shaped as slice along pulmonary veins. The veins of the blood vessels were obscure and the edges were unclear. In TPT treated group,there were multiple high density images shaped as tubercle and slice and the boundary were not clear. In XFC treated group, the lungs' outlines were clear and the veins were welldistributed. High density images shaped as spot were found in part lungs.

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

Early in 1995, in his "Desire" series where red and blue lines come in strong contrast with each other, Ma Yiping instinctively used his personal experience to drop a hint of the transcendence of life. From 1996 to 2001, his "Images" series established the development direction of his art, owing to its artistic expression_r_r of overloaded psychological priori images. In his works before or after 2003, dream-like symbolic images presented perplexed feeling of human beings about the universe and the physical world. In his "images" series in 2006, uncertain images stood on black cube-shaped objects and ambiguous edges pointed to various uncertain directions with the accompaniment of silver light and shadow. At this point, the intuitive perception of the essence of nature made his artistic style gradually take shape. In his later "fetish" series, in which he gradually became mature in spiritual and symbolic expression_r_rs, Ma Yiping fully grasped the eternal sense of the spiritual world.

在早期，1995年的《欲望》马一平用对比强烈的红色、蓝色层层涂盖、本能地运用自身感受以暗示的手法表达对生命的超越。1996-2001年以物象为主题的系列作品对超载心理先验物象的表达方式确定了他艺术作品的发展方向，2003年前后的作品中，梦一般的暗示性物体程现了生命本体对宇宙物理世界的茫然，在2006年的《物象》系列中，黑色的方体上不确定的物状、模糊的边缘在泛着银色光影的衬托下，泛生着各种不确定的指向感，此时对本质直观的感知性的把握使作品艺术风格基本形成，到后来的《神物》已经充分地把握了精神世界里的永恒感，画面中所能达到的精神性和神密暗示意义的表现手法已近成熟。
