Experimental results show that the proposed method can achieve better performance than the fixed threshold histogram method 实验结果表明其性能优于广泛采用的固定阈值肤色检测方法。
Some normalization methods are discussed in detail , including histogram method , expectation - variance method and trend surface analysis 这里详细介绍了各种测井数据标准化的方法原理,并给出了相应的实例。
Compared with the fixed threshold histogram method used widely , this method can find optimal thresholds to the different complex backgrounds 相对于固定阈值的直方图检测方法,该算法可以针对不同的图像内容产生相应的最优分割阈值。
The fast wavelet entropy technique for image indexing to reduce the complexity of the wavelet histogram method is suggested which can improve the retrieval performance 提出了快速小波熵的图像检索技术以减少小波直方图技术的计算复杂性并提高了检索速度。
In chapter 3 , a new method , which called general histogram method , is presented . the performance of this new method is proved much better than the normal histogram method 接着在第三章中给出了一个新的基于广义图像的广义直方图检索算法,实验结果表明新的算法相对于传统的直方图方法在检索输出精度上有较大提高。
