摘要
简要介绍了红外热像仪测量涂层发射率的原理,详细介绍了基于红外热像仪的涂层波段发射率测量装置设计与测试方法,实际测试发射率0.708～0.920之间的4个标准样品,误差均不大于2.06%。
We introduced an infrared image denosing model based on Contourlet domain hidden Markov trees（CHMT） in terms of the fact that the infrared image Contourlet subbands coefficients satisfies the GGD（Generalized Gaussian Distribution）model. The algorithm applied to some kinds of infrared images and compared both in infrared image vision effect and peak value signal to noise ratio, the new algorithm shown better results especially in edge maintenance aspect.
