论新自由主义对中西传媒业的影响

新自由主义的推行带来的是西方传媒业管制渐进放松,随之出现了前所未有的大兼并、集中、整合的现象和超级跨国传媒公司的产生,多数人看到的只是新自由主义给西方传媒带去的繁荣和快速发展,而很少有人发现新自由主义给西方传媒带去的还有民主的丧失、新闻自由的虚伪、公共利益维护的缺位、公平正义平等理念的歪曲。二十多年来的中国传媒改革在很大程度上也受到了新自由主义思潮的影响,但我们必须明确,中国传媒产业改革应当在批判吸收新自由主义理论的基础上,走出一条中国式的改革之路。     

A bintree energy approach for colour image segmentation using adaptive channel selection

A new hierarchical approach called bintree energy segmentation was presented for color image segmentation. The image features are extracted by adaptive clustering on multi-channel data at each level and used as the criteria to dynamically select the best chromatic channel, where the segmentation is carried out. In this approach, an extended direct energy computation method based on the Chan-Vese model was proposed to segment the selected channel, and the segmentation outputs are then fused with other channels into new images, from which a new channel with better features is selected for the second round segmentation. This procedure is repeated until the preset condition is met. Finally, a binary segmentation tree is formed, in which each leaf represents a class of objects with a distinctive color. To facilitate the data organization, image background is employed in segmentation and channels fusion. The bintree energy segmentation exploits color information involved in all channels data and tries to optimize the global segmentation result by choosing the ＂best＂ channel for segmentation at each level. The experiments show that the method is effective in speed, accuracy and flexibility.     

现有世界文化遗产桥梁的核心价值及中国古桥申遗的思考

中国古代桥梁具有极高的技术成就,然而迄今为止,我国尚没有古桥被列入世界文化遗产,因此开展中国古桥申报世界文化遗产的研究非常必要。为了加快我国古桥申遗的进程、促进我国古桥的保护与传承,从世界遗产的相关定义与要求出发,介绍被列入世界文化遗产桥梁的特点,对我国古代桥梁的价值与技术成就进行讨论。根据世界文化遗产入选的条件,我国的古代石拱桥和木拱桥最具有申遗实力。依据桥梁作为功能性结构、技术复杂结构的特点,在此基础上提出中国古代桥梁申报世界文化遗产应聚集核心技术内容的研究,突出其核心价值和技术成就。

Segmentation of complex objects'' sonar images using parameter-fixed MRF model

The effective method of the recognition of underwater complex objects in sonar image is to segment sonar image into target, shadow and sea-bottom reverberation regions and then extract the edge of the object. Because of the time-varying and space-varying characters of underwater acoustics environment, the sonar images have poor quality and serious speckle noise, so traditional image segmentation is unable to achieve precise segmentation. In the paper, the image segmentation process based on MRF (Markov random field) model is studied, and a practical method of estimating model parameters is proposed. Through analyzing the impact of chosen model parameters, a sonar imagery segmentation algorithm based on fixed parameters' MRF model is proposed. Both of the segmentation effect and the low computing load are gained. By applying the algorithm to the synthesized texture image and actual side-scan sonar image, the algorithm can be achieved with precise segmentation result.
