【正文】 論文選題的理論意義論文選題來(lái)源于在圖像工程中 指將數(shù)學(xué),光學(xué)等基礎(chǔ)學(xué)科的原理, 程的內(nèi)容非常豐富,根據(jù)抽象程度和研究方法等的不同分為三個(gè)層次:圖像處理,圖像分析和圖像 12 所示,在圖中,圖像分割處于圖像分析與圖像處理之間,其含義是,圖像分割是 從圖像處理進(jìn)到圖像分析的關(guān)鍵步驟,也是進(jìn)一步理解圖像的基礎(chǔ).圖像分割對(duì)特征有重要影響. 圖像分割及基于分割的目標(biāo)表達(dá), 特征提取和參數(shù)測(cè)量等將原始 圖像轉(zhuǎn)化為更抽象更緊湊的形式, 使得更高層的圖像分析和理解成為可能. 而邊緣檢測(cè)是圖像分割 的核心內(nèi)容, 所以邊緣檢測(cè)在圖像工程中占有重要的地位和作用. 因此邊緣檢測(cè)的研究一直是圖像 技術(shù)研究中熱點(diǎn)和焦點(diǎn),而且人們對(duì)其的關(guān)注和投入不斷提高.。 而屋頂狀邊緣位于灰度增加與減少的交界處. 在數(shù)學(xué)上可利用灰度的 導(dǎo)數(shù)來(lái)刻畫邊緣點(diǎn)的變化,對(duì)階躍邊緣,屋頂狀邊緣分別求其一階,二階導(dǎo)數(shù). 對(duì)一個(gè)邊緣來(lái)說(shuō),由一個(gè)平面變化 到法線方向不同的另一個(gè)平面就會(huì)產(chǎn)生階躍邊緣。 paper selected topic theory significanceThe paper selected topic originates in holds the important status and the function practical application topic in the image socalled image project discipline is refers foundation discipline and so on mathematics, optics principles, the discipline which in the image application unifies which accumulates the technical background image project content is extremely rich, and so on divides into three levels differently according to the abstract degree and the research technique: Imagery processing, image analysis and image shown in Figure 12, in the chart the image division is in between the image analysis and the imagery processing, its meaning is, the image division is from the imagery processing to the image analysis essential step, also is further understands the image the foundation. The image division has the important influence to the image division and based on the division goal expression, the characteristic extraction and the parameter survey and so on transforms the primitive image as a more abstract more pact form, causes the highlevel image analysis and possibly understands the edge examination is the image division core content, therefore the edge examination holds the important status and the function in the image the edge examination research always is in the image engineering research the hot spot and the focal point, moreover the people enhance unceasingly to its attention and the investment.167。 But the roof shape edge is located the gradation increase and the reduced intersection portray the peripheral point in mathematics using the gradation derivative the change, to the step edge, the roof shape edge asks its step, the second ti
