论文摘要
详细研究了对图像上微生物对象进行计数的密度图方法（DM）方法的统计特性。 DM由U $^2 $ -NET给出。使用了深层神经网络的两种统计方法：引导程序和蒙特卡洛（MC）辍学。对DM预测的不确定性的详细分析导致对DM模型的缺陷有了更深入的了解。根据我们的调查，我们提出了网络中的自称模块。改进的网络模型，称为\ textIt {自称密度映射}（SNDM），可以单独校正其输出密度映射，以准确预测图像中对象的总数。 SNDM体系结构的表现优于原始模型。此外，两个统计框架（Bootstrap和MC脱落）都对SNDM均具有一致的统计结果，在原始模型中未观察到。 SNDM效率与检测器碱模型相当，例如更快和级联R-CNN检测器。
The statistical properties of the density map (DM) approach to counting microbiological objects on images are studied in detail. The DM is given by U$^2$-Net. Two statistical methods for deep neural networks are utilized: the bootstrap and the Monte Carlo (MC) dropout. The detailed analysis of the uncertainties for the DM predictions leads to a deeper understanding of the DM model's deficiencies. Based on our investigation, we propose a self-normalization module in the network. The improved network model, called \textit{Self-Normalized Density Map} (SNDM), can correct its output density map by itself to accurately predict the total number of objects in the image. The SNDM architecture outperforms the original model. Moreover, both statistical frameworks -- bootstrap and MC dropout -- have consistent statistical results for SNDM, which were not observed in the original model. The SNDM efficiency is comparable with the detector-base models, such as Faster and Cascade R-CNN detectors.
