摘　　要：首先根据二值图像隐藏算法的特点和应用需求,提出了评估二值图像隐藏算法的指标集,该指标集包括隐藏容量、视觉效果、图像失真、嵌入效率、统计特性和时间复杂度。其次,应用该指标集对5种典型的二值图像隐藏算法进行评估和比较。最后根据实际应用需求设定相应的指标权重,对算法进行综合评估。该评估方案不仅能对新的二值图像隐藏算法进行性能评估,还可以从已知算法中选择最优算法,并为进一步的研究与改进提供方向。This paper presents an index set for evaluating information hiding algorithms based on bi- nary image according to their characteristics and application requirements. The index set includes hiding capacity, visual effects, image distortion, embedding efficiency, statistical characteristics and time complexity. The index set is also used to evaluate and compare five typical information hiding algorithms based on binary image. Finally, a comprehensive assessment of the algorithms is made af- ter setting up the appropriate index weight according to the actual application needs. The new assessment program not only can evaluate the performance of the information hiding algorithm based on binary image, but also can help to choose the best one from all the known algorithms, and provide the directions for further research and improvement.
