本文是針對影像作移動物體偵測。現今有非常多的方式對視訊監控影像作移動偵測的方法，在物體移動中，大部分最常見的方法是對物體找出特定的特徵點，並在兩張影像中計算此特徵點的移動，但有時這些特徵點有時候會較難被定義清楚，因為物體移動的時候容易使影像模糊，特別是在影像無法事先得知的情況下更為困難。
在本文主要是使用加速穩健特徵(SURF)演算法來定義移動物件的特徵點，因為SURF 偵測特徵的速度相對於SIFT 來說會比較快，但是不管是SIFT 還是SURF，在檢測的物體移動時，匹配結果則不如預期中良好，因為物體在移動時可能存在著不正確的特徵點，所以本文提出了邊緣和特徵偵測去作結合，以此提高特徵匹配的情況，除此之外本研究中我們各種不同的移動方式做偵測去計算正確的特徵點並做分析。在實驗中，我們可以進一步的了解此方法相較於傳統的方法上，能有更良好的辨識能力。

This thesis is detecting object for moving images. Nowadays, there are many methods for moving object detection on surveillance, and the method used is to find features and then to use the motion of those features between images to calculate features points moving. But the feature points sometimes are more difficult to define because the objects moving are easy to make images blur. Especially, when the objects may not be known in advance.
In this thesis, using SURF algorithm defines the features of motional images because it detecting speed is faster than SIFT. But whether it is SIFT or SURF when the detected object moves, the matching result is not as good as expected because the objects may have incorrect feature points on moving. In the thesis, we provide edge and feature detection to combine for increasing the feature matching. In addition, this study we use a lot of different detection to detect and calculate the correct feature points to analyze. In experiment, we can further understand our methods getting the better ability to identify compared to the traditional methods.
