Measurement method for digital image stabilization based on randomness test
|
Abstract:
This paper proposed a measurement method for digital image stabilization based on randomness test. Firstly,estimated the global motion vectors of the video stabilized by a digital image stabilization method.Then converted the global motion vectors into a series of binary sequence. Finally,utilized pseudorandom test to measure the randomness of the binary sequence and measured the stability of the stabilized video by using the randomness of the binary sequence. The experiment shows that the proposed method can measure the digital image stabilization methods exactly.
