为优化视频配准工作中的静态图像配准算法,本文应用深度学习的卷积神经网络VGGNet设计了一个静态图像配准算法。通过仿真实验结果可知,VGGNet能够被很好地应用于静态图像配准工作中;结合均方根误差和

结果可知,基于Conv5、FC1或者FC2输出特征的静态图像配准算法具有良好的性能,基于FC2的配准算法性能最好,其均方根误差值为0.031 22,
N

值为74。通过视频缩放和亮度转换后,静态图像配准算法的性能有所下降,在亮度变换后基于FC2输出特征的配准算法性能较高。与传统HOG、LBP特征提取的图像配准算法相比,本文算法具备较好的配准精度和正确率。研究结果可为当前基于深度学习卷积神经网络的静态图像配准算法提供参考。
In order to optimize the static image registration algorithm in video registration
a static image registration algorithm based on deep learning convolutional neural network VGGNet is proposed. The simulation experiments results show that VGGNet can be well applied to the static image registration work. Combining the root mean square error and
N

results
it can be seen that the static image registration algorithm based on the output features of Conv5
FC1
or FC2 has good performance. The algorithm based on FC2 has the best performance with root mean square error value of 0.031 22 and
N
red
of 74. After video scaling and brightness conversion
the performance of the static image registration algorithm decreases. The performance of the registration algorithm based on FC2 is better overall after the brightness conversion. Compared with the traditional image registration algorithm based on HOG and LBP feature extraction
this algorithm has better registration precision and accuracy. The research results can provide a reference for current static image registration algorithms based on deep learning convolutional neural networks.
