Pattern analysis and machine intelligence, 1999, 21 : 1312 - 1328. 3 shen d, wong w, ip h h s. affine - invariant image retrieval by correspondence matching of shape
第三，全局的圖象結構相比局部圖像特徵對噪聲更魯棒，但對圖像畸變卻更敏感。 -
Third, this paper makes full use of the correlation of color components of a color image. this method uses fractal affine transform combined with correlation of color components
3利用彩色圖像三個色彩分量之間存在的密切的相關性，提出將上述分形壓縮演算法結合圖像三分量之間的相關系數聯合進行圖像編碼。 -
Abstract an improved image recognition and registration algorithm based on convex hull and affine invariant was presented
摘要提出了一種新的基於凸殼和仿射不變量的圖像識別和配準的方法。 -
On the basis of the new affine transformation and self - adapted quadtree im - age compression method, we bring forward a new image compression method. experiments show that the psnr can reach 28. 7db at the compression ratio of 22. 4 for 256 x 256 x 8 " lena " image, better than jacquin [ 1 ], fisher [ 13 ] and yao zhao [ 12 ] ' s method. at last, we point out the defects of the method and program, bring forward some ways to be improved
並介紹了用此演算法編寫的程序，給出了實驗結果，實驗結果顯示「 lena 」 256 256 8圖象在psnr等於28 . 7時，壓縮比可以達到22 . 4 ，比fisher ， jacquin ，和趙耀等人的結果都有一定程度的改進，文章最後指出了演算法和程序的不足，提出了一些改進的方向。 -
Second, the edge points on the scan - lines of the first prewarped image are detected and the corresponding points on the same scan - lines of the other prewarped image are matched. third, with these corresponding edge points, the scan - lines of the two images are segmented. in the end, more exact corresponding relation of these points are obtained under the use of the affine transformation and the auto - corresponding of the images are finished
該演算法首先矯正源視圖，使矯正後圖像滿足視點平移關系；然後檢測第一幅圖像掃描線上的邊緣點，再由這些邊緣點匹配出第二幅圖像上對應的邊緣點，利用這些對應的邊緣點再分割兩幅圖像中所對應的掃描線；最後用仿射變換建立較為準確的點與點的對應關系，完成圖像的自動匹配。 -
Note that in fractal encoding, each range block is to compare with domain blocks after some grey - level affine map. hence we first put forward a kind of image quadrature invariant of affine maps above, which can be thought of a generalization of mario feature
由於在分形編碼時值域塊實際上是與經過灰度仿射變換之後的定義域塊進行比較，因此我們首先提出了一種在灰度仿射變換下保持不變的圖像矩不變量，它可看作是mario特徵的推廣。 -
However, it was not until 1990s " that p. d. e. was systematicly introduced to the field of image processing, and formed a relatively integrated theory system combined with other mathematic tools such as mathematic morphology and affine geometry
但直到九十年代才比較系統地將偏微分方程引入圖像處理領域，結合其他一些數學工具如數學形態學和仿射幾何等，形成了比較完整的理論體系。 -
In this technique, an image is usually represented by a contractive affine transformation, for which the reconstructed image is its fixed point and approximate to the original image. the fractal code of the image consists of the parameters of the contractive transformation
在分形編碼中，一幅圖像由一個使它近似不變的壓縮仿射變換表示，重構圖像是壓縮變換的不動點，壓縮仿射變換的參數組成原始圖像的分形碼。 -
This method is very well suited to handle the occasions that the object in the image has undergone an affine transformation and is partly covered
該方法的優點是即使目標物體被部分覆蓋或者缺損，其圖像也能夠達到較好的識別和配準效果。 -
The essence of affine reconstruction is to compute the infinite homographyo the key to metric reconstruction is identification of the absolute conic image, in the end we give a experiment
最後實驗分別給出了仿射重構的結果和歐氏重構的結果。實驗表明我們的演算法是有效的和可行的。
