  1. The exploitation and study of this system have got great success, compared with the ones of the same type, this system is more open and more easily used to merge with cad and cam, it runs stably, is convenient to be maintained and the interface is friendly and intuitional. its usage can be grasped quickly. according to the input information, it can automatically display different properties of nc codes in different colors, and zoom in or zoom out the figure of tool nose paths dynamically

    本系統的開發研究已取得實質性成果，與國內同類的數控系統相比，具有真正的開放性，易於實現與cad cam軟體集成，運行穩定，維護方便，界面友好直觀，易學易用，能根據輸入自動顯示不同顏色以區廣西大學頎士學趕文募于； m咖ss平臺肘開俠尤三劫肛前喊在系統開發研窮分代碼的屬性，能動態縮放顯示刀具軌跡圖形，此外，它有較好的多任務性和獨立性，能在加工時執行其它windows應用程序而不影響加工，控制器甚至能在pc端操作系統關閉時繼續完成加工，可用軟體控制面板或硬體操作面板兩種方式操縱機床。
  2. In fact, scaling technology is an essential component in many image / video processing such as to magnify / minify still image, to achieve special effect like picture - in - picture, to compress or transform digital video with spatial scalability etc. in this thesis we mainly employ this technology in video transcoding, which is a powerful but computationally intensive tools to convert one kind of video format into another, meeting different demand such as lower bitrates or various display terminals. in sum, there are two kinds of scaling schemes : one is in spatial domain and the other in transform domain. the scheme in transform domain can provide very good performance, that is, efficient computation and desirable image quality, whereas it has some disadvantage which is impossible or hardly to o vercome, especially some scenarios require arbitrary ratio zoom in horizontal and vertical, and excellent visual effect

    兩種方法都各有其利弊：變換域的方法是利用現有常用的視頻壓縮方案都是基於dct這個特點，所以可以直接在變換域做處理，這樣可以節省大量的計算，但其缺點是由於dct是基於塊的變換，如8 8 ，所以很難找到一種方案可以進行任意比例的縮放，尤其是在縱橫縮放比例不一致的情形，但這對諸如hd縮放到sd和空域分級的壓縮方案來說尤為重要，基於空域濾波的方法卻沒有這樣的限制，同時可以保證縮放后的圖像的質量遠高於基於變換域的方法，為了達到高的縮放質量，就不可避免導致計算量過大。
  3. The arithmetic expressed in this text solved contradiction between the watermark ' s transparence and the arithmetic ' s maleness, using the inlaid watermark of that arithmetic having goodly transparence, and the result of the experiment shows the arithmetic has goodly maleness to jpeg compress, noise, low channel filter wave, mosaic, signal tone up, secondary watermark, cut and zoom, especially to sharpen, strengthen contrast, strengthen edge, equilibrium, and so on, signal strengthen can hardly effect to get away the watermark

    實驗表明，本文演算法較好地解決了水印透明性與演算法魯棒性之間的矛盾，使用該演算法嵌入的水印具有較好的透明性，同時本文演算法對jpeg壓縮、噪聲、低通濾波、馬賽克、信號增強、二次水印、剪切和縮放等操作有較高魯棒性，特別是銳化、對比度增強、邊緣增強、直方圖均衡等信號增強處理幾乎不影響水印的抽取。
