I could see the colors, not the faces. they stood in contrast to the grayness and became, i thought, a busy human rainbow
我看不清他們的臉龐，只能看到繽紛的色彩。這些色彩與灰暗的天色形成了對比，在我看來，繁忙的人流好似交織成了一道彩虹。 -
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 -

The question was answered for him, and so oppressed was he by the grayness of life that he forgot the tentative proposition she had made for him to go to work. and she, having gone as far as she dared, was willing to wait the answer till she should bring the question up again
灰色的生活阻擋了他，使他忘卻了她在試圖要求他去工作，而她呢，既已說明了想法，冒了險，也願意等下一次再要求回答。 -
The hurley side of the family all tend towards premature grayness, but our caroling would have none of that, so she bought a rich brown hair - coloring agent and, after messing up the bathroom totally, emerged looking gorgeous, with brand new hair
哈雷這家人都傾向于未老頭發先白，但我們的卡羅琳娜將不原這樣，因此她買了一管豐富的棕色染發劑，在整個搞亂了浴室之後，她從里邊出來，一頭嶄新的亮發，光彩照人。
