在联合冲击滤波器和非线性各向异性扩散滤波器对含噪图像做预处理的基础上，利用边缘检测算子选取自适应参数，构建能同时兼顾图像平滑去噪与边缘保留的自适应全变分模型，并基于Bregman迭代正则化方法设计了其快速迭代求解算法。实验结果表明，自适应去噪模型及其求解算法在快速去除噪声的同时保留了图像的边缘轮廓和纹理等细节信息，得到的复原图像在客观评价标准和主观视觉效果方面均有所提高。 —————————————————————————————————— This paper combined shock

Previous research found that the pupil diameter (PD) can be an indication of affective state, but this approach to the detection of the affective state of a computer user has not been investigated fully. We propose a new affective sensing approach t
