In this paper, we propose the chord - distribution - based image description, and research the image retrieval algorithm based on this description. the main work of the paper consists of two part that are the feature description about image and the algorithm of image retrieval. in the first part, we propose the definition of region - chord, the presentation of chord - distribution, and describle image after analyzing the properties of chord - distribution. in the second part, after partitioning image and counting region - chord - distribution, we analyse the forground and background of image to each region and propose the criterion of the similarity of images

A statistical method is used to obtain the background model, which is updated real time in order to adapt to illumination changes and scene changes. after threshold operation, morphologic operation and connected region area measurement are introduced to solve background disturb problem. at last, shadows are detected using hsv color space information and gets exact moving regions
該方法首先利用統計的方法得到背景模型,並實時地對背景模型進行更新,以適應外界光線變化和場景本身的變化,閾值操作后,用形態學和連通域檢測的方法進行后處理,消除噪聲和背景擾動帶來的影響,最後,在hsv顏色空間下檢測出陰影,得到準確的運動對

In this method, the construction of an object by fragments is somewhat similar to the assembly of a jigsaw puzzle, where we try to put together a set of pieces such that their templates form an image similar to a given example
該方法將含有對象區域的子圖作為對象基元,類似於拼圖游戲一樣利用對象基元在圖像中拼接覆蓋出對象區域,進而實現對象分割。
