基于信号分析的椒盐噪声滤波算法

椒盐噪声对图像造成或亮或暗的像素点,从视觉上影响图像的质量。采用基于信号分析的方法去除图像中的椒盐噪声,信号分析能准确判断出噪声与信号像素,该方法依据椒盐噪声模型准确区分信号与噪声,对信号像素给予保留,而对于噪声像素则有针对性地对其作中值滤波、扩大的中值滤波或均值滤波。实验结果表明,与线性加权、梯度倒数加权以及小波去噪算法相比,文中算法能有效降低图像中的椒盐噪声,对图像的边缘与细节保持较好,并且能得到较高的信噪比。

《逍遥游》与庄子的人生观

《逍遥游》的结构并不是什么有待——无己——无待,也并非意义不连贯。历来庄学家注重探微,都没有说对,把《逍遥游》倒过来读,问题就很清楚。一篇《逍遥游》,从头到尾,就是个大小之辩。庄子以大鹏自喻,以九万里云风比喻其境界之高远宏大,为大而辩护,从而开启了一场大小之辩。大小之辩是《逍遥游》全篇的线索、主题和宗旨,其核心思想就是知有大小。庄子所推崇的大知,就是至人无己,神人无功,圣人无名,最高境界是无己的境界。庄子所说的知的不同,就是人生境界的不同。庄子所谓有所待或无所待,不是指存在论意义上的条件,而是指人生论意义上的系著与留恋。     

扫罗与撒母耳冲突原因初探——对《撒母耳记》的多视角解读

扫罗是以色列第一位君王,撒母耳是犹太人历史上最后一位士师,两者处于从士师时代到王国时代过渡的特殊时期。因而,作为上帝权能代表的先知撒母耳和世俗王权代表的扫罗之间就不可避免地存在着矛盾和冲突,冲突的产生有撒母耳个人心理方面的因素,也与历史政治大环境对王权的呼唤和王国建立初期的政教冲突有关。     

“深情”与“无情”——中西文论的一个比较

文学理论是文化的载体。深受天人合一观念影响的中国古代文论是深情的,与之相比,主客二分、主客二元对立观念影响下的西方文论则显得较为客观,较为无情。这种深情和无情对比主要表现为三个方面:一是善与真的不同,二是情与理的差异,三是文学与哲学的区别。中西文论的不同反映了中西文化的差异。比较中西文论的不同,旨在展开中西文化的对话,求同存异,促进中国现代文论的建设,从而使中国文论屹立于世界民族文化之林。
