An adaptive motion decision system for digital image stabilizer based on edge pattern matching
Joonki Paik, Yong Chul Park, Dong Wook Kim · IEEE Transactions on Consumer Electronics · 1992
The effects of various environmental conditions which degrade the performance of a digital image stabilization (DIS) system in a video camera are analyzed. On the basis of the analysis, a new DIS system with an adaptive motion decision system is proposed. The DIS system is composed of (i) a local motion vector generation unit, (ii) a field motion vector generation unit, (iii) an accumulated motion vector generation unit, and (iv) field memory address control and a digital zooming unit.>
