To segment multi - object image , n - region segmentation problem is equivalent to n - 1 two - region segmentation problems that are solved based on the developed simple m - s model . the experiments show that cytoplasm of immune cell is segmented out 實驗結果表明,與小波- fcm模糊聚類紋理圖像分割方法相比,該方法對雙紋理圖像能取得較好的分割效果,分割出的邊界連續,并且具有較強的抗噪能力。
On the base of the study on si / sige hetero - junction fast switching power diode , two kinds of novel structure of sige / si pin diode are proposed in abstract this paper . the one is the gradual changing doping concentration in the n - region , and the other is sige pin diode with mesa structure 本文在對sige si異質結快速開關功率二極管的研究基礎上,提出了兩種sige si快速開關功率二極管的新結構: ?基區漸變摻雜型sige異質結開關功率二極管和臺面結構sige異質結開關功率二極管。
On the base of the study on sige material physics characteristic , sige / si hetero - junction characteristic , we dissertate the advantage of sige / si hetero - junction power diodes and establish more accurately physical models and propose two novel kinds of fast and soft recovery p + ( sige ) - n - - n + hetero - junction power diodes : the one is p + ( sige ) - n " - n + diode with the multiplayer gradual changing doping concentration in the n - region , and the other is p + ( sige ) - n " - n + diode with ideal ohmic contact on the cathode interface 本文針對sige材料的物理特性、 sige si異質結特性建立了準確的物理參數模型。在詳細論述了sige si異質結功率二極管良好特性的基礎上,提出了兩種快速軟恢復sige si功率二極管新結構: n ~ -區采用多層漸變摻雜和陰極側采用理想歐姆接觸。
