本文针对两种构建二维直方图的方式进行了分析及对比试验.通过构建灰度级-平均灰度级二维直方图和灰度级-梯度二维直方图并进行理论分析,然后由最大熵法对几幅不同的图像进行分割得出试验结果,验证之前的分析.试验表明：对于有噪声的图像,灰度级-梯度二维直方图最大熵法的效果要明显优于灰度级-平均灰度级,它不仅抵抗噪声稳健,同时能使分割后的图像区域内部更均匀、边界形状更准确.本次试验对二维阈值分割的研究有较大意义.

According to the two construction of two-dimensional histogram method is analysis and contrast test. Through the construction of gray level - average gray level histogram and gray level-gradient two-dimensional histogram are analyzed in theory, and then by the maximum entropy method for a few different image segmentation result of the experiment, validation prior to analysis. Experiments show that: for noisy images, gray level-gradient two-dimensional histogram maximum entropy method the effect was better than that of gray level - average gray level, which is not only robust noise resistances, and can make the image segmentation region more homogeneous, more accurate boundary shape. The test of two-dimensional threshold segmentation is of great significance to the study of
