The two key steps in image mosaic process are image registration and image fusion. The common SIFT algorithm needs complicated calculation, which wastes too much time in practical image registration. This problem is solved in this paper by giving the feature point in SIFT a more accurate main direction. Thus, the SIFT can be more easily used. Based on this improved SIFT algorithm, a new image mosaic...
To determine whether it is necessary to perform bilateral varicocelectomy (BV) in infertile men with left clinical and right subclinical varicoceles by comparing the outcomes of BV with those of left varicocelectomy (LV) in these patients.A total of 104 infertile men with left clinical and right subclinical varicoceles were randomly divided into 2 groups: BV (n = 51) and LV (n = 53).
