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The resonant box effect is the most important. in chapter five, we use the experimental setup constructed and the cavity decay time method to measure the total loss of a passive resonant cavity, and analyse the experimental data in very detail. we conclude that, in present experimental conditions it is the uniformity and stability of laser mirror to confine the precision and repeatability of experimental results
