查询词典 a priori

A region superresolution spectrum estimation method based on coventional DFT computation is presented for obtaining one dimensional range profile, which has the advantages of real-time in computation and robustness under clutter and noise background over general superresolution methods. A iterative extropolation method based on both priori knowledge provided by conventional DFT spectrum and matching filtering process of target return data is also presented for range profile processing, which has the advantages of robustness in improving range resolution, suppressing clutter and noise.

在目标一维距离成像谱估计中，提出了以常规DFT为基础的邻域超分辨谱估计方法，它与普通超分辨算法相比，具有实时性强、在杂波与噪声背景中稳健性好的优点；在外推成像处理中，提出了以常规DFT目标结构图像为约束条件并结合目标信号准匹配滤波处理的迭代外推算法，其优点是稳健性好，能适度地提高距离分辨力但保留适度的抗杂波抗噪声能力。

This paper proposed a new algorithm for eyes detection in the images. First, in a known face image, the homomorphic filter was used to enhance the contrast of the image and the iterative thresh choosing algorithm changed the gray images into binary ones. According to certain priori knowledge, it could get the candidate field of the eyes.

因此，我们讨论了在相同已知信息的情况下，即最优加权最小二乘估计也利用有关被估参数的先验信息时，二者的估计性能。

In the introduction, the condition of the importation and research of romanticism in Chinese in the first 50 years of the 20th century is reviewed, and there exist two main evils: On one hand, Chinese theorists tend to have some priori knowledge before their study, they always compare the so-called"original state"of romanticism in the western with the modern Chinese romanticism, thus they deny the possibility of Chinese romanticism. Under such condition, no-theoretical system of romanticism appeared in China, we have neither broken away from the hegemony of the western literature, nor have we grasped the modern Chinese romanticism in a whole. On the other hand, we hold a mechanical idea that romanticism develops itself from the conflict with the classicism、the realism、the modernism, so the essence of the romanticism is subjectively and lopsidedly established, that makes the concept of romanticism lose its function as a symbol.

在绪论中，主要回顾了20世纪前50年我国理论界对浪漫主义的引进与研究状况，引出了我们面前对浪漫主义研究中出现的两大弊端：一是理念的先验性，以所谓西方"原汁原味"的浪漫主义理念来比照、言说中国现代浪漫主义文学，从而形成了一种否定现代中国浪漫主义存在的理论倾向，既没有形成象勃兰兑斯对欧洲十九世纪浪漫主义的"本土式"的言说，没有真正摆脱西方文学霸权话语的阴影，形成自己的浪漫主义理论体系，也没有完成对现代中国浪漫主义的整体把握；二是以一种"意图伦理"的姿态，机械地认定浪漫主义是从与古典主义、现实主义和现代主义的冲突中建立起来的，主观而片面地确认中国现代浪漫主义的内涵，使浪漫主义概念越来越混乱而空泛，已经停止履行一个词语符号的功能。

Through establishing the priori estimates for the approximation solutions, we pove the existence of global generalized solution by using the compactness principle and obtain the global property for the generalized solutions in the space L〓. At the last, a new method is used to prove the uniqneness which is a good results, at some extense, under generalize conditions.
