An Image fusion method based on segmentation region is proposed in this paper. First, the source images are decomposed by wavelet to get the approximate and detailed sub-images, and the segmentation by watershed method for these sub-images are used to get the regions of each level, these regions are used to guide fusion process. The activity level and match(More)
BACKGROUND Information on the health-related quality of life (HRQoL) of patients with genital warts (GW) in populations in mainland China is still limited. The aim of the study was to use a generic instrument to measure the impact of genital warts on HRQoL in men and women in this setting. METHODS A multi-centre hospital-based cross-sectional study across(More)
In this paper we present a new fusion technique to increase the information content of the fused image. We propose information fusion by maximizing the wavelet entropy using windowing technique. It helps to diagnose the diseases like tumor, cancer …etc effectively. The images are decomposed by wavelet transform and using maximum selection rule the low(More)
The mechanisms governing the development of cardiac pacemaking and conduction system are not well understood. In order to provide evidence for the derivation of pacemaking cells and the signal that induce and maintain the cells in the developing heart, Nkx2.5+ cardiac progenitor cells (CPCs) were isolated from embryonic heart tubes of rats. Endothelin-1 was(More)
The aim of the present study was to provide reliable experimental evidence for the application of autologous skin fibroblasts (asFbs) in the repair of depressed scars. In the experiments, depressed trauma was induced in male Wistar rats, and fibroblasts were separated from the removed skin tissues to culture in medium. In vitro cultured asFbs were injected(More)
BACKGROUND Although periodic blood shortages are widespread in major Chinese cities, approximately 1 x 10(5) U of whole blood are discarded yearly because of under-collection. To reduce the wastage of acid citrate dextrose solution B (ACD-B) anticoagulated under-collected whole blood (UC-WB), this study was performed to elucidate the effect of extracellular(More)
