This paper illustrates detailedly the thin groupware auto - adaptive recognition system ; it also illlustrates the procession of capture image and take indispensable foreclose to wipe off noise in order to get boundary easilyer. the recognition system uses " hough " transform method to make the recognition area orientation, and according to the unstable environment such as lights which leads to the change of the image ' s brightness, thresholds picture using an iterative selection method and then growing process for cell image segmentation based on local color similarity and global shape criteria, adaptively gets the best threshold to divide the washer off the background. the recognition system uses the classifier based on minimal - error - ratio bayes method to make decision after getting image characteristic
本文詳細介紹了薄形組合件自適應識別系統；闡明了圖像的分通道自動採集過程，以及對採集到的原始圖像所進行的預處理方法。通過採用哈夫變換去除偽邊緣點的方法，有效地解決了識別區域的定位問題。針對裝配零件（主要是墊片）薄、小導致圖像信息少、識別難度大，以及材質不一導致採集到的組合件圖像亮度波動等問題，提出了使用最佳閾值迭代法和使用種子填充的圖像串列分割技術，自適應地找出最佳閡值，使墊片和背景分離，從而提取墊片數目信息。 -
Through stress, displacement straight - line picture and the strain ratio of two supports before it cracks, the stress and displacement fields of symmetric and asymmetric samples under static conditions are observed
通過裂紋啟裂前的應力、位移等直線圖及兩個支座的應變之比，觀察靜態條件下對稱試件及非對稱試件裂紋面兩端的應力場和位移場。 -
In width. to maintain the proportions of the original picture, also select the lock aspect ratio check box
若要維持原有的寬高比不變，還可選中「鎖定縱橫比」復選框。 -
It is estimated that by 2029, this ratio will be as high as 309, that is every 3 persons in the working force have to support one older person. this is no doubt a vivid picture for a society facing a rapid ageing process
及至六十年代末，為回應社區的需要，各志願機構即現時的非政府機構紛紛引入外國新的服務模式，例如：社康護理、家務助理及老人宿舍等。 -
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。 -
At first, carrying on varying the gray level of the picture which is gathered by ccd system in order to strengthening the contrast ratio between the target and background ; and smoothing the picture in order to getting rid of the noise which is produced by gathering and transmitting, so that we can detect the edge easily
文中首先對ccd系統採集進來的圖像，進行灰度變換，增強靶標與背景的對比度；並對圖像進行平滑處理，去除圖像採集和傳輸中混入的噪聲，以利於圖像的邊緣檢測。 -
There are two innovations in the hardware system in currency sorter field. one of the innovations is that the powerful chip lpc2210 of arm series is applied on the test instrument for liquid crystal display module. and expand external memory ensure the large data volume because the ratio of small size tft - lcd and the quantity of test picture are increasing. because the powerful capabilities of processing datum of lpc2210, the test instrument is much faster and higher performance / price ratio than traditional test instrument and portable. the other one is the test instrument combine the
本系統在該領域的創新點有兩點，一是將高性能arm核心晶元lpc2210應用到液晶顯示模塊測試系統中，並通過外部擴充存儲器，滿足了小尺寸tft面板在解析度不斷提高，測試畫面增加的情況下對測試系統大數據容量的需求。且由於arm系列晶元強大的數據處理能力，使得該測試系統相對傳統的測試機速度更快，性價比更高，且更加輕巧。
