This algorithm solves the problem of IR image details reduce and the loss of gray level while using algorithm of gray threshold segmentation and eliminates the random noise and background noise around the IR object successfully,achieves a remarkable effect of the denoising.
针对基于双材料微悬臂梁FPA红外成像系统中的图像噪声,提出了离散量和平均灰度的红外图像实时处理算法,解决了灰度阈值分割法在去除噪声的同时滤除掉目标物体像素、使红外图像细节丢失且灰度级减少的问题,在目标物体像素损失较小的情况下,去除了目标物体周围的随机噪声及背景噪声,提高了信噪比。
