-
The digital information is easy to process by pc. this paper introduces the stereo matching techniques in msv system, including image pre - processing, feature abstraction, stereo matching and depth information acquiring. in order to obtain images easy to detect objects " edges, images have to processed by the techniques such as guass smoothing and image enhancement
針對顯微圖像的特點，對圖像進行了高斯平滑和圖像增強處理，有效的抑制了隨機噪聲對圖像處理的影響，提高了物體與背景的對比度，有效的實現了物體與背景的分離，為邊緣檢測特徵提取，立體匹配提供良好的圖像信息。 -
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，對采樣數據的預處理進行討論，包括采樣數據的標度變換、采樣數據的數字濾波、剔除采樣數據中的奇異項、去除或提取采樣數據的趨勢項、采樣數據的平滑處理等數據處理方法。 -
Chapter two explores the pre - processing and segmenting of medical images. as the medical images are interfered by noises more or less, it is needed to restrain noises by filtering and smoothing
第二章的內容是醫學圖像預處理及體數據分割，獲取的圖像或多或少有噪聲的干擾，預處理的目的就是對其進行適當的處理，如濾波、平滑等，以實現噪聲抑制。 -
The practical methods of signal pre - processing ( anti - disturbance filtering, data smoothing ) and character extraction ( differential limitation, absolute peak value, peak - to - peak value, area of wave and self - adaptive threshold adjustment ) are introduced
並介紹了一些實用的信號處理和特徵提取演算法，包括可以實時運算的用於抑制干擾的濾波器和數據平滑演算法及用於定量分析的差分超限數、絕對峰值、峰-峰值、波形下面積和自適應門限調整等演算法及其應用。 -
After histogram transform, enhancement, smoothing, pre - segmentation, edge extraction and thinning, we get an image with clear edges. after extracting of feature units, we describe the shape of airports with straight - line segments and distinguish different objects with the length of the lines, which can achieve the computer - aided auto - recognition of airports
經過直方圖變換、圖象增強、圖象平滑、圖象預分割、邊緣提取和細化后，得到了清晰的邊緣信息圖象，通過特徵基元的提取和識別，用直線段來描述直線狀目標，而用直線段的長度來作為目標定量特徵的描述，可以實現遙感影像機場目標的計算機識別。 -
A modified synchronization approach by using sliding windows is proposed. the pre - processing for obtaining principal eigenvectors is a smoothing procedure for the dsss signal. the computer simulations show that the approach is more convenience in low snr comparing with other code synchronization methods
3 、提出了一種改進滑動窗的盲同步方法，該方法利用求主特徵向量的過程，對擴頻信號進行平滑降噪預處理，實現了較低信噪比下的碼同步。
