Paper Abstract

This paper presents a real-time digital image stabilization algorithm on PC to stabilize a sequence of images. The proposed algorithm can be divided into 3 steps. First step is to acquire an appropriate bit plane. It is easier and faster to compute with bit plane than original image. Second, through histogram processing, we can match cursorily. lfthere are error matches, we can use a block matching algorithm to match again to acquire exact result. Then the local motion vector can be obtained from it. If we apply inline MMX assemble language hybrid programming, we can make it faster on PC. Last, we eliminate the field motion vector produced in irregular conditions. Through this step, we can void local motion vectors affected by undesirable condition such as moving objects. The characteristic of this algorithm is fast and effective. By it, real-time digital image stabilization can be realized on PC.
