在不同室内定位算法中,传统WKNN算法原理简单易于实现,但基于该算法的定位结果往往存在定位误差较大、精度不高等问题.为了克服这种不足,将改进的WKNN算法引入室内定位.此方法通过观测每项实测值与存储值的差异量,赋予修正权重值来减少错误信号强度值对整体指纹距离的影响,经实验结果表明,改进后的WKNN算法能够有效减小室内定位误差,优化室内定位精度.

鱼类X射线图像大多存在对比度较低,鱼刺不明显的特点。文章研究了常用的图像增强方法,包括直方图均衡、巴特沃斯高通滤波器等。在此基础上,文章提出了计算像素点局部邻域内的最大值和最小值,并利用最大值和最小值得到自适应参数,建立对比度增强函数,并利用该函数公式增强图像。实验结果表明,文章提出的方法能有效提取鱼类X射线图像中的鱼刺,具有较好的视觉效果。
