Paper Abstract

In outdoor surveillance systems, block matching is usually used for image stabilization but prohibited for real-time video rate application due to its tremendous amount of calculation burden, though many strategies induced to save searching time. In this paper, a faster and robust image stabilization technique is presented to eliminate the unwanted video motion during watching time. Unlike other image stabilization algorithms using two projection vectors in each x or y direction, we use only one projection vector to estimate the translation motions in 2 directions between image sequences. Our stabilization algorithm compare the template vector with vectors in the referenced vector matrix constructed and find out the minimum vector-wise MSE. At last, inspired by the block matching method, we introduce its searching strategies into our algorithm to decrease the computation times, thus making real-time video stabilization could be implemented on normally available PC.
