Optimal Extraction Method of Feature Points in Key Frame Image of Mobile Network Animation

Abstract In order to effectively extract the feature points of mobile network animation images and accurately reflect main content video, an optimization method key frame is proposed. Firstly, frames are selected according change degree video. The scale invariant transformation algorithm used describe image local estimated by constraint realize extraction animation. efficiency analyzed from number effectiveness extraction, time-consuming similarity invariance points. experimental results show that proposed has excellent adaptability, can image.
