4.Due to knowledge representation method based on set of rules, forward and backward chaining, depth-first search and the comparison between the diagnosis result deduces by the system and detailed diseases information, the system realized the function of diagnosis, consultation and learning on vegetable diseases.
采用能够全面、系统、层次性地表述专家知识的“规则架+规则体”的规则组知识表示形式、正反向混合推理策略、深度优先搜索策略、以及系统诊断与用户对照详细资料相结合的方法,较好地解决了农业领域知识的复杂性和不精确性,成功实现了温室蔬菜主要病害的诊断、咨询和学习功能,集实用性、方便性和科学性于一体。收藏指正
5.Two methods of edge detection and segmentation based on partial differential equation(PDE) are introduced,they are Snake Model and Level Set Methods. We worked out Euler equation corresponding to Snake using variational method and proved non-stability of the three discrete schemes which are forward differential,backward differential and center differential. We detectd the edge of microscopic cell image by constructing algorithms with upwind differential scheme.
利用变分法推导了图像边缘检测Snake模型对应的Euler方程,证明了水平集方法3种离散格式(向前差分、向后差分、中心差分)的不稳定性,采用迎风差分格式构造水平集算法,对显微细胞图像进行边缘检测,实验结果表明,该算法是稳定的和收敛的.收藏指正
