摘要：
This article aim at the application of the high real-time required embedded terminal situation, an improved SIFT algorithm is proposed. After traditional SFIT algorithm get the stable points, global texture description was carried out on the key points of frequency domain by contourlet transform, select the top 1% of points, and then through a kind of nearest neighbor search algorithm based on Vector Angle (Vector Angle, VA) to match. This algorithm improves precision, speed and the accuracy of the embedded terminal.
