點特征是圖像最基本的特征,它是指那些灰度信號在二維圖像上都有明顯變化的點,如角點、圓點等。點特征可以應用于諸如圖像的配準與匹配,目標描述與識別,光束計算,運動目標跟蹤、識

摘要在圖像理解、圖像匹配、三維重建及模式識別等領域中,特征點的檢測具有十分重要的意義。特征點在保留圖像中物體的重要特征信息的同時有效地減少了信息的數據量,使得對圖像處理時運算量大大減少。特征點的的定義有多種不同的表述,如圖像中灰度值和像素劇烈變化的點、圖像邊界上具有較高曲率的點等。對于特征點的定義決定了特征點的特性,同時也決定了所檢測出的特征點的檢測所采用的方法。35079
點特征是圖像最基本的特征,它是指那些灰度信號在二維圖像上都有明顯變化的點,如角點、圓點等。點特征可以應用于諸如圖像的配準與匹配,目標描述與識別,光束計算,運動目標跟蹤、識別和立體像對3D 建模等眾多領域。使用點特征進行處理,可以減少參與計算的數據量,同時又不損害圖像的重要灰度信息,在匹配運算中能夠較大的提高匹配速度,因而受到人們的關注。提取點特征的算子稱為興趣算子或有利算子(interest operator) ,即利用某種算法從影像中提取人們感興趣的有利于某種目的的點。在圖像分析和計算機的視覺領域,根據不同應用目的選擇有效的點特征提取。

 Abstract
   In image understanding, image matching, 3D reconstruction and pattern recognition, the detection interest point of great significance. interest point objects in an image while preserving the important characteristic information effectively reduces the amount of data, so that the image processing operations of the greatly reduced. Define the characteristics of a variety of different points of expression, such as image and pixel gray value of point dramatic changes, and so has a point higher curvature on the image border. For the definition of the interest point determine the characteristics of the feature point, but also determines the method of detecting the detected interest point used. 源`自*六)維[論*文'網www.aftnzs.live
Point feature is the image most basic features, which are those on the two-dimensional image signal gradation has significant change points, such as corners, dots and so on. Point features can be applied to image registration and matching, object description and recognition, beam calculation, moving target tracking, identification, and many other fields, such as three-dimensional image of the 3D modeling. Processed with the point features can reduce the amount of data involved in the calculation, without compromising important information grayscale image, in matching calculation can greatly improve matching speed, and thus subject to people's attention. Feature extraction point operator is called operator or beneficial interest Operators (interest operator), namely the use of an algorithm to extract people from the image point of interest in favor of a particular purpose. In the field of image analysis and computer vision, and choose effective point feature extraction depending on the application purpose.
Keywords:    interest point; interest operator; interest point of image detection algorithm
