Generally, traditional edge detection methods don't consider the spatial relationship between the adjacent image areas to extract the edges. For the traditional algorithm insufficiency, this paper purposes a novel edge detection algorithm by introducing spatial relationship. This method can be divided into three main steps: firstly, a measure of similarity between pair wise pixels is taken into account...
Exploration and development of the deep part coal resource have important strategic meanings for Chinese economic. However, the seismic of strata in deep part is always suffering from the decline of resolution. To overcome this problem, we propose a method to improve resolution of seismic data by spectrum whitening in time-frequency domain. Compared with conventional algorithm, our method enhances...
