交叉熵 meaning in Chinese
cross entropy
Examples
- Motion region detection based on cross entropy in image sequences
图像序列中基于交叉熵的运动区域检测 - We do a lot of experiments on the representative fusion schemes , and use entropy , cross entropy , mutual information to evaluate the performance of them
选取其中有代表性的算法进行了大量实验，并用熵、交叉熵、交互信息量等多种评价方法进行了定量分析与比较。 - The results show that when evaluated with the indexes of cross entropy and contrast , it performs better than the wavelet transform based fusion method with the fusion rules of maximum absolute coefficient and maximum directive contrast
仿真实验表明，较之于基于最大绝对系数和最大方向对比度的小波变换融合方法而言，该方法在交叉熵和对比度意义上性能更佳。 - Several evaluation criteria of information entropy , across entropy , psnr , average square difference and definition are presented in this dissertation . using these evaluation criteria , we study that different fusion rules influence the image fusion performance . these evaluation criteria are also applied to compare the performance of various image fusion methods
定量的评价图像融合性能是一项重要而复杂的工作，建立了信息熵、交叉熵、峰值信噪比、均方差以及清晰度这几种评价方法和准则，利用这些评价准则，研究不同的融合规则对融合性能的影响，还利用这些评价规则对多种图像融合方法的性能进行了比较研究。
