Visual representation ; associative code ; top - down information processing ; inferior temporal lobe and prefrontal lobe
視覺表徵聯想性編碼頂-底信息加工顳下回皮層和前額葉皮層 -
The key to the fft algorithm is the design of butterfly computation and that of the address logic. the whole schema is designed in the top - down design flow and described in the vhsic hardware description language ( vhdl ), basing on these, we do our research on reconfigurable technology. the result indicates that the data processing ability of reconfigurable system improved greatly
結果表明，可重構系統在數據處理能力方面比以往的系統有了很大的提高，本設計實現的fft重構處理器可工作於60mhz下，完成一個16點fft需要132個主時鐘周期，完成32點fft需要324個主時鐘周期，而且具有一定可重構性，可以方便地將其運算點數進行擴展，或將其他的圖像處理演算法在實時處理系統中實現。 -
Bottom - up processing and feature detecting theory based on strong electrophysiological evidences has played a dominant role in the visual research for long time. people know top - down processing just by common sense. knowledge or experience are recalled from memory by reactivation of their neural representations and affected visual processes. however recently, researches from human and monkey provide experimental evidences for top - down processing. first, mnemonic representation of visual objects and faces, located in the ventral processing stream of visual perception in monkey, provide the best evidences of how neuronal codes are created by neurons that have the special ability to link the representations of temporally associated stimuli ; second, experiments suggest that not only bottom - up signals from the retina but also top - down signals from the prefrontal cortex can trigger the retrieval of associative codes, which may serve as a neural basis both for the conscious recall and for the visual processes affected by top - down processing further studies will improve people s understanding of the causal relation of activation and behavior by use of combined fmri and electrophysiology or lesion studies
聯想性編碼是通過學習由一些具有特殊功能的神經元建立的，這些神經元具有將時間性關聯刺激的表徵聯系起來的能力。其次，不僅來自視網膜的底-頂信號，而且來自前額葉的頂底信號都能觸發聯想性編碼的提取，既可以作為有意識回憶的神經基礎，又是頂-底加工影響視覺過程的基礎。腦損傷病人研究具有高時間解析度的人類功能性核磁共振成像functional magnetic resonance imaging ， fmri和猴fmri研究以及猴細胞電生理分析相結合，將進一步加強人們對視覺腦機制的全面理解。 -

還在介紹紅外運動目標檢測與跟蹤系統組成的基礎上，詳細討論了圖像數據採集部分的結構，圖像數據的預處理， dsp與fpga之間的通訊和fpga對其他器件的控制邏輯等。 -
The general idea given by schematic theorists is that reading comprehension is an interactive process between the readers " background knowledge and the text ; an interaction of bottom - up and top - down processing, in which content schema and formal schema work simultaneously
在我校高中英語教學中，閱讀教學的問題尤其突出。為了提高閱讀教學效果，通過實驗的方法對高三學生的閱讀教學進行了探索。 -
The ideal for future extensibility in dtds for technical information or any information that is continually exploited at the leading edge of technology is to build the fewest possible presumptions about the top - down processing system into the design of the dtd
對于技術信息（或在前沿科技上持續開發的任何信息）而言， dtd中未來擴展的理想作法是將有關自頂至下的處理系統的最少可能化假設構建到dtd設計中。 -
Individuals make use of both real world knowledge and linguistic knowledge to identify the meaning of propositions. cognitive theory suggests that effective processing of text requires the use of both top - down and bottom - up processing
