image reconstruction

基本解釋

Image reconstruction from projections is a very hot research area all over theworld.
由投影數(shù)據(jù)重建圖像一直是國際學(xué)術(shù)界研究的熱點之一。
In case of no way to make synchronizing between the flash and the rotating, one has to identify the angle of all the random projections on the Sinogram before doing CT image reconstruction.
在閃光無法與旋轉(zhuǎn)物體角移嚴(yán)格同步時，為進行CT圖像重建，需對這些隨機投影的投影角進行識別和確定其在正弦圖上的位置。
It is introduces how to analyze the fault in the data acquisition and image reconstruction system, also list service examples of this system.
本文介紹了數(shù)據(jù)采集系統(tǒng)、圖像重建和顯示系統(tǒng)的故障診斷方法及具體故障的維修實例。

圖像質(zhì)量
Wavelet image compression methods can maintain a high quality image reconstruction under the prerequisite of high compression ratio. And wavelet transformation coding technology is widely used in image compression.
基于小波變換的圖像壓縮方法能在高壓縮比的前提下保持好的重建圖像質(zhì)量,小波變換的編碼技術(shù)被廣泛地應(yīng)用于圖像的壓縮中。
影像重建

圖像重建
So it is nature that conbine the wavelet theory with image reconstruction.
因而，圖像重建和小波分析理論的結(jié)合成為一種自然的結(jié)果。
圖像后處理
Besides,selected 30 pations randomly to carry on CT convention scan and spiral CT image reconstruction,compare the potences of these two methods as pairing data.
另外隨機選擇30例病人行CT常規(guī)掃描和螺旋掃描后圖像后處理,作為配對資料進行兩種方法的優(yōu)勢性比較。

The simulation results show that the proposed hierarchy transmission system improves the image reconstruction quality effectively without using additional resources.5、This paper put forward several coding and decoding methods and signal detection methods.
仿真實驗證明了所提出的分級傳輸系統(tǒng)在不使用額外資源的情況下,有效的改善了圖像重構(gòu)質(zhì)量。 5、提出了幾種通信系統(tǒng)中編碼解碼和信號檢測改進方法。
圖象恢復(fù)
圖像復(fù)原
This paper based on the traditional technology that combination image processing with microscopic measurement, in view of the deblurring image, applied image reconstruction in microscopic measurement technology, intensified the precision . The main contents of this thesis are as follows:1.
本文基于傳統(tǒng)的圖像處理與顯微測量相結(jié)合的應(yīng)用技術(shù),針對于不是很清晰的圖像,把圖像復(fù)原引入顯微測量技術(shù),提高了測量精度。

Finally, the paper attempts to explore the possible limitations which hampered image reconstruction, namely, cultural defaulting and cultural misreading.
最后，論文還探討了妨礙意象重構(gòu)的制約因素，即文化缺省和文化誤讀。
