Most resent approaches to the problem employ noise estimate or Signal-Noise Ratio (SNR) estimate, and hence their performances depend on the estimation of noise.

目前的处理方法普遍需要估计噪声或者信噪比，从而其性能依赖于噪声估计的好坏。

Raw thermal images acquired by pulsed thermography(PT) usually have low signal noise ratio(SNR) and temperature contrast.

脉冲热像检测中直接获取的原始热像往往信噪比较低、对比度较差。
