【摘要】 提出了一种基于降采样模型的显微热图像高分辨力重建算法,该算法通过与三次样条插值放大得到的像素点相比较以补偿微扫描产生的系统误差。仿真和实验结果表明,提出的方法减少了由于微扫描误差所带来的图像重建质量下降,提高了光学微扫描显微热成像系统的空间分辨力,具有较强的实用价值。提出的方法还可以应用到其他光电成像系统中以提高系统空间分辨力。更多还原

【Abstract】 A new high-resolution reconstruction algorithm is proposed based on the downsampling model.Comparing with the pixel obtained from cubic spline interpolation,the errors generated by microscanning system can be compensated.The simulations and experiments are conducted.Our main results that the image reconstruction degradation due to the errors generated by the microscanning are reduced.The technique can improve the thermal microscope imaging quality effectively and has a strong practical value.The technique can also be applied to other electro-optical imaging system and improve its resolution.更多还原
