摘　　要：人机交互嵌入式图形用户界面容易受到噪声影响,且受传输带宽的限制,处理图像较为复杂,导致视觉增强效果不佳。为此,提出人机交互嵌入式图形用户界面视觉增强方法。利用傅里叶变换方法处理人机交互嵌入式图形用户界面,获得边缘像素集,融合区域特征,分层提取用户界面。采用均值滤波处理方法分析透射率,去模糊处理用户模糊界面。基于此,利用Retinex和小波变换图像增强方法获取去模糊后的视觉图像饱和度,计算亮度分量,增强处理去模糊处理后的视觉图像。由实验结果可知,该方法能够获取清晰用户界面,且噪声振幅在-1.5~0.8 dB范围内波动,说明使用该技术抑噪效果最好。The embedded graphical user interface(GUI)is susceptible to noise and limited by transmission bandwidth,so its image processing is complicated,which results in poor visual enhancement effect.Therefore,a visual enhancement method for embedded GUI of human⁃computer interaction(HCI)is proposed.Fourier transform method is used to process the embedded GUI of HCI,so as to obtain the edge pixel set,fuse the regional features and extract the user interface by layers.The transmission rate is analyzed by means of mean filtering,and the user fuzzy interface is deblurred.On this basis,Retinex and wavelet transform image enhancement methods are used to obtain the saturation of the deblurring visual image,calculate the brightness component and enhance the deblurring visual image.The experimental results show that the proposed method can obtain a clear user interface,and the fluctuation of noise amplitude can be kept within-1.5~0.8 dB,which indicate that the proposed technology has the best noise suppression effect.
