Lifting scheme can be used to calculate discrete wavelet transform ( dwt ) efficiently, it is composed of a number of lifting steps and the scaling transform 提升方法是計算離散小波變換的有效手段,它由提升步和拉伸變換組成。
The text is reflected using a scaling transform, but first a new origin is set to prevent the text from being drawn outside the viewable area of the form 文本是使用縮放轉(zhuǎn)換反射的,但首先要設(shè)置新原點,防止將文本繪制到窗體的可視區(qū)域之外。
Pslift first calculate all lifting steps of each level and each dimensional dwt, and then calculate the scaling transform . for example, when five level decompositions is implemented for cdf 9 7 wavelet, compared to the known methods, the number of multiplication needed is reduced by 20 % and 28 % corresponds to one dimensional dwt and two dimensional dwt, respectively 例如,對圖像與視頻壓縮中應用廣泛的cdf9/7小波,做一維5級分解時與現(xiàn)有方法相比,乘法運算量減少20,而做二維5級分解時,乘法運算量可以減少28。
Using wavelet-based multi-scale transform to detect infrared target, it is possible to acquire modulus image to segment citrus from background under direct sunlight conditions, whereas it is difficulty to identification because of the confusion of the reflected light from leaves under backlighting . the method is very sensitive to the ambient air condition, such as in condition b or c, the identification is very difficult 用該方法可以較好地識別順光條件下采集的紅外熱圖像中的果實,而在背光條件下,由于位于樹冠邊緣的樹葉反射光較強或穿過樹冠的光使周圍的樹葉光反射較強,使果實在紅外熱圖像中的溫度或灰度低于反射光強的樹葉等部分,則不能識別。

Chapter 5 introduces sampling-holding device principle, types and main performance parameters . we discussed the relationship between the sampling and the s-h device . chapter 6 discussed the pre-processing of sampling data including the scale transforming, digital filtering, reducing oddity and eliminating or pick-up tread item as well as smoothing process of the sampling data 在第6章,對采樣數(shù)據(jù)的預處理進行討論,包括采樣數(shù)據(jù)的標度變換、采樣數(shù)據(jù)的數(shù)字濾波、剔除采樣數(shù)據(jù)中的奇異項、去除或提取采樣數(shù)據(jù)的趨勢項、采樣數(shù)據(jù)的平滑處理等數(shù)據(jù)處理方法。
The thesis summarizes many methods that were excogitated in these several decades, in which wavelet transform has favorable time-frequency localization, scale transform and direction characteristic, and it has been a convincing tool for texture analysis as it can adapt mortal seeing system much easily 文章總結(jié)了幾十年來,人們提出的許多紋理分析的方法。其中小波變換具有良好的時頻局部化、尺度變換和方向特征,更容易適應人類視覺系統(tǒng),它已成為紋理分析的一個有力的工具。
Recently, bureau of national broadcast largely promotes the digitalization of broadcast and television . a number of local governments, beijing, shanghai, tianjin, chongqing, hainan, ningbo, xiamen, fuzhou, quanzhou, linxi, mianyang start to carry out the full scale transform of digital television 今年數(shù)字電視“整體轉(zhuǎn)換”將全面開花,北京、上海、天津、重慶、海南、寧波、廈門、福州、泉州、臨沂、綿陽等一大批省市將開始“整體轉(zhuǎn)換”,數(shù)字電視增值業(yè)務將開始真正“增值”。
