CCD图像的轮廓特征点提取算法

采用最大方差法将图像二值化,用图像形态学的梯度﹑细化和修剪算法来提取边缘轮廓,利用十一点曲率法得到轮廓的角点和切点的大致位置。提出了一种基于最小二乘拟合的改进算法,来进一步确定角点和切点,并对轮廓分段识别。该算法应用在基于图像处理的刀具测量系统中,实际结果表明具有良好的抗噪声性能,能准确提取出图像的特征点。

Changes in Sexual Distress,Depression and Sexual Function after Clitoral Reconstruction in Women with Female Genital Mutilation/Cutting

Abstract

Background: Female genital mutilation/cutting (FGM/C) links health complications and psychological distress. However, there is scarce literature on how women with FGM/C respond to treatment interventions. Objective: In this study, we aimed to assess changes in depression symptomatology, sexual function, and distress following clitoral reconstructive surgery combined with a psychoeducational intervention. Methods: The reconstructive surgery consisted of recovering the remaining clitoris and placing it externally and as close to the vagina as possible. FGM/C patients (n?=?27) received psychological support and sexual counseling upon undergoing the surgical intervention and were further assessed at 6-month follow-up. Moreover, they completed the Beck Depression Inventory and the Female Sexual Distress Scale Revised at these two time points. Patients’ sexual dysfunction was assessed according to DSM-5 criteria. Results: Statistically significant clinical changes after FGM/C were reported. Overall, patients presented reduced depression and sexual distress levels, and decreased female sexual interest/arousal disorder prevalence. Results also revealed that sexual distress improvements were more significant in Type I FGM/C patients. Conclusions: Significant improvements in sexual distress, psychopathology, and sexual function were observed in our sample following reconstructive surgery, suggesting that combined interventions are effective for treatment.     

论“断水、断电”作为行政强制执行方式的正当性

＂断水、断电＂是督促当事人履行义务的有效手段,能在当前水污染防治中发挥重要作用。对目前已有规范进行分析后发现,它对若干基本权利构成限制,与最小侵害原则不符。然最小侵害仅为比例原则组成部分,乃警察法时代控权理念的产物。时代背景变迁后,它已不再单独具有评判管制措施合法性的功能。＂断水、断电＂作为一种行政强制执行方式,至少在我国当前的水污染治理领域中具有正当性。
