Secondly, because the operator is associativity, so it is possible to avoid the boring complicated letters thirdly, because the association of resolution and paramodulation is generalized complete, we can use the infimum of the operator to gradually close the false level of cause set. so it is not necessary to choose threshold before resolution and paramodulation. the operator is got from every resolution and paramodulation

  7. Entropy of an image is to express the smoothness or homogeneity of the image. while computing in a local window, if there exist edges, the local image will not be homogenous, variation of the grayness will be sharp and the entropy obtained will be low. otherwise, the entropy will be high. given the threshold of entropy, it can be determined whether or not exist edges. because entropy operator is sensitive to noise, the effect is bad if it is directly used to detect edges. in view of the deficiency, the paper comes up with an edge detection method in which entropy operator is combined with noise removal. if the entropy computed is higher than the threshold, it will be necessary to determine whether it is caused by noise or by edges. thus edge detection and noise removal can be made at the same time. with this method satisfactory effect has been achieved by experimenting upon image with low ratio of signal to noise

    圖像的熵用來刻劃圖像的平滑性或均勻性.在圖像的局部窗口中計算時,如果窗口中存在邊界,則窗口中的圖像不均勻,其灰度變化急劇,計算出的熵小;反之熵大.設定熵的閾值,即可判斷是否存在邊界.由於熵運算元對噪聲很敏感,直接用它進行邊界檢測,效果很差.文中針對這一缺陷,提出將熵運算元與去噪相結合的邊界檢測法,如果計算出的熵大於閾值,要判斷是噪聲的出現所引起,還是邊界的出現所引起,這樣,邊檢測邊界邊去噪聲.用該方法對信噪比較低的圖像進行實驗,得到了滿意的效果
