Fractal coding has been proved useful for image compression. it is also proved effective for content - based image retrieval. in the paper, we present a block - constrained fractal coding scheme and a matching strategy for content - based image retrieval. in this coding scheme, an image is partitioned into non - overlap blocks of a size close to that of a query iconic image. fractal codes are generated for each block independently. in the similarity measure of fractal codes, an improved nona - tree decomposition scheme is adopted to avoid matching the fractal codes globally in order to reduce computational complexity. our experimental results show that our coding scheme and the matching strategy we adopted is useful for image retrieval, and is compared favorably with other two methods tested in terms of storage usage and computing time
分形編碼在圖像壓縮方面取得了很好的效果，同時，分形編碼也能夠用於基於內容的圖像檢索.本文提出了一種基於塊限制的分形編碼演算法和匹配策略，並將它們用於圖像檢索.在我們編碼演算法中，圖像會被預先分成互相不重疊的子圖像塊，然後對這些子圖像進行獨立地分形編碼，從而獲得整幅圖像的分形碼.該編碼演算法能夠在很大程度上減少編碼時間.在進行圖像間相似性的匹配時，我們採用改進的基於九叉樹的分配策略，從而避免全局地進行分形碼的匹配，減少了計算量.實驗結果說明，我們的編碼演算法和匹配策略能夠比較有效地應用於基於內容的圖像檢索，在計算時間和存儲時間上都優于實驗中其它兩種方法 -

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
