Compressed sensing (CS) has been increasingly used in the synthetic aperture radar ground moving-target indication system, particularly for imaging the moving targets, which satisfy the sparse precondition of the CS method. However, efficient moving-target imaging is a key challenge for current CS methods, since the redundant basis brings heavy computation load. In this letter, by exploiting the geometry...
Ratio of carbon to nitrogen (C/N) in leaves, defined as the ratio of LCC (leaf carbon concentration) to LNC (leaf nitrogen concentration), is a good indicator for synthetically diagnosing the balance of carbon and nitrogen, nutrient status, and growth vigor in crop plants. So it is very significant for effective diagnosis and dynamic regulation of crop growth in field to monitor changes of leaf C/N...
Blind restoration of blurry image is a challenging and significant problem. In this paper, we propose a deblurring algorithm which restores the latent image from a single blurry image. The method consists of two parts, kernel estimation and image restoration. To estimate the blur kernel, a cost function is constructed using a regularization term based on normalized sparsity measure and a fast optimization...
Fingerprint ridge distance is a very useful parameter in AFIS (automatic fingerprint identification system), it can be used for fingerprint enhancement, identification or classification. In this paper, a new ridge distance estimation method based on the ridge search is presented. Firstly, we use the IPL(initial points line) to select the initial-points line. Then, we follow ridges with the search...
In order to search for the gap between Chinese oil enterprise and international oil companies in the marketing force, use the close value method to evaluate the marketing force of nine major oil companies in the environment of Excel. Find out that there are differences in the close value of the nine major oil companies and the level of every company's marketing force orders one by one by analyzing...
