zoom picture
解釋
全屏模式-
Scientists can also ask the computer to zoom in on certain small areas of the picture.
科學家還能要計算機很快移向圖片上某些小區域內。 -
Double - tap to zoom - in and zoom - out you can view the picture in actual size and fit - in - screen size by double - tapping the image
只需要雙擊屏幕就可以從圖片的實際解析度和滿屏狀態之間輕松切換。 -
Thirdly, decrease the difficulty of the character recognition through studying the method of character preprocessing ; at last, some effective methods of feature extraction, such as the one based on image transform with the invariant features which keep stable while the picture move, rotate and zoom in or out, and the other focused on the shape of character and features of direction
三、深入探討了字元識別的預處理方法，減少字元識別時的運算量和難度。四、討論了三種特徵向量的提取方法，一種是基於平移、旋轉和尺度不變性的圖像變換法，一種是計算中心矩的方法，再就是強調字元形狀和結構的方向特徵量提取法，實驗中通過最小距離法進行字元的分類識別，匹配時間少，識別率有所提高。 -
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。 -
Wavelet analysis have many advantages over discrete fourier transform by zoom - in and zoom - out capability. wavelet denoising in multi resolution approximation has been evolved to become very powerful tools for digital picture signal processing
去噪處理已成為研究重點。小波多解析度逼近分析去噪已發展成為圖像處理的一個重要而有效的工具。 -
Photofusion can replace the built - in camera, cell phone management tool increase is a lot more exciting and professional functional design, such as : four times digital zoom, the whole picture production
Photofusion完全可以替代手機內置的攝像頭管理工具，並且增加了許多較為專業的功能和令人激動人心的設計，如： 4倍數碼變焦全景象製作等。 -
The main duty of image manipulation module is to deal with the patient ' s foot picture captured by camera and then mapping final clear outline to main client. the model displaying module ' task is to display the orthosis on the main client and translate, rotate, zoom and mirror the orthosis. it also can change the viewport of the orthosis. the model modication module has a serial of function which can be modified the orthosis according to the situation of different patients. this article expound the wanton smooth area ' modification in detail from two aspects
圖象處理模塊主要是把攝像頭獲取的病人足底信息進行圖像處理，最終把明顯的輪廓信息映射到主視圖窗口；模型顯示模塊主要是顯示矯形器，並且可實現對矯形器的平移、旋轉、縮放、鏡像、渲染及視圖變換等；模型修改模塊是針對千差萬別的病人情況而確定的一組修型功能，本文對模塊中的任選區域修型功能從區域選定及區域編輯兩方面作了較為詳細的論述。
