文中提出了利用圖像灰度線性變換來抑制背景圖案噪聲的影響,突出圖像邊緣信息;然後採用簡單統計法進行邊緣檢測,得到邊緣特徵信息圖;最後通過對邊緣特徵信息圖在寬度方向上進行均勻劃分成不同的區域,統計不同區域的邊緣特徵點的數目作為神經網路的初始輸入向量,對初始輸入向量用隨機掩碼處理和遺傳演算法進行優化得到最終輸入向量,通過三層bp神經網路分類器進行分類,達到了人民幣識別的目的。The third chapter of the thesis makes a study of the equation of interest rate - amount, of circulating fund on limited occasions of sudden events, proves that the network average interest rates of different time periods are also different and change with the impulsive conditions, and makes clear the relationship between the network average interest rates of two neighboring time periods. as far as every node in the network is concerned, its instant interest rate will tend to, in the end, at the sum of the basic interest rate of every node and the growth rate of the network
本文第三章研究了出現有限次突發事件時的利率?流通量方程,證明了不同時間段的網路平均利率也不相同,並且,隨脈沖條件的變化而變化,同時給出了相鄰兩個時間段網路平均利率之間的關系,就網路中每個結點而言,其即時利率最終穩定於結點基本利率與網路增長率之和。In order to further video analysis, an algorithm of abrupt shot boundary detection based on fuzzy clustering neural network ( fcnn ) is proposed, and it has the advantages of high precision as well as robust to fast move. caption segmentation is the key to the whole process, fcnn can also be utilized to locate caption region, however, the technique is time - consuming. thus an improved projection segmentation method is presented, and the experimental results show that it is simple and practical, and fits for real - time processing
為了便於后續的視頻分析,提出了一種基於模糊聚類神經網路( fcnn )的鏡頭突變檢測演算法,實現視頻鏡頭分割,該演算法具有檢測精度高、對運動穩健等優點;區域定位是字幕提取的關鍵一環,同樣利用fcnn分類器可實現字幕定位,但其運算量大,定位精度不高,因此提出了一種改進的投影分割方法實現字幕區域定位分割,實驗表明其簡單實用,適于實時處理;考慮到單個字元背景相對簡單,為此提出了一種基於單字元的字幕二值化演算法,最終在經由字元分割、二值化及殘留背景像素清除之後,得到了清晰、高質的字幕圖像,字元識別結果證明了這一點。In the steven spielberg film, tom hanks plays viktor navorski, a traveller from a fictional east european country stuck in new york s jfk airport terminal after his passport is revoked following a coup back home. in the big screen version, hanks character romances a glamorous stewardess played by catherine zeta - jones
