由于人带有主观因素,每个人的评价可能都不一样,因此有必要用几种客观的评价方法来对结果进行评价。目前,用得比较多的评价方式是MSE(Mean-Squared Error,均方误差)和PSNR(Peak Signal-to-Noise Ratio,峰值信噪比)。 两幅M×NM×N大小的图像u(x,y)u(x,y)和v(x,y)v(x,y)的MSE计算公
在上一篇文章中,我们讲了使用积分图来加速NL-means算法,虽然运算耗时减少了好多,还是没达到毫秒级。所以本文在积分图加速的基础上,进一步使用CUDA来并行加速,使得耗时减少到毫秒级。 使用积分图来加速NL-mean…

Neuroligin 1 (NLGN1 or NL1) is one of several type I transmembrane Neuroligin proteins that play an important role in synaptic development (1). Mature human Neuroligin 1 is an N- and O-glycosylated 120 kDa molecule that consists of a 649 amino acid (aa) extracellular domain (ECD...
