域的边缘

In this paper, a new edge detection method——method using extremum of first directional derivative is proposed, based upon a general gradient edge model.

文中通过傅里叶变换，在频率域，通过求垂直于边缘的一阶方向导数，并检测其极值点来确定边缘。

Firstly, nonlinear diffusion filter was used to wipe of noise efficiently and kept the edge information of the image. Secondly, gradient calculation of pixel diagonal direction was considered in the calculation of neighborhood gradient amplitude which further repressed the impact of noise. Thirdly, using average interclass variance, the self-adaptively double thresholds for different images were calculated.

首先采用非线性扩散滤波减少了图像噪声，同时保持图像的边缘信息；在邻域梯度幅值计算中，考虑像素对角线方向的梯度，进一步抑制了噪声的影响；最后采用平均方差阈值法选取阈值，从而提高了对不同图像的自适应性。

The wavelet transform is an important tool in the domain of mathematic ...

小波变换是一种强有力的数学和信号处理工具，它的时频域特性决定了它在图像的边缘检测中具有很好的应用前景。

The permo-carboniferous coal measures in North China Basin were formed under the condition of epicontinental sea which was characterized by the extreme gentle slope and high frequency of sae-level changes, the contemporaneous margin portion of which was probably very far or had been destroyed during the proccess of plate subduction and continental collision. The lowstand systems tract, therefore, has not be discovered up to now.

华北晚古生代内陆表海古地貌上表现出的极缓的基底和海平面的高频变化，具有特殊性，其同期的边缘海部分可能距离很远或在板块消减及大陆碰撞过程中被破坏掉，因而至今未发现低位体系域存在的证据。

The algorithm in this paper is based on territory value segmentation of the junction region. The algorithm makes use of edge detection to distill the region of the edge, and conducts domain segmentation, then comminutes the pixels of regional at the junction each region strictly, transfer the similar color to the same region.
