In this paper, a novel method for the digital image stabilization is proposed that use variance properties (VDIS) to reduce the computational cost of block matching algorithm for local motion estimation. This method based on calculation of variance of pixels in each frame and accumulated variance of each pixel in each location from first reference frame to current frame. Then calculate summation of...
There are many methods for digital image stabilization. In this paper, a fast algorithm for the digital image stabilization is proposed that use background small area for digital image stabilization. Background areas are some parts of image that have not motion object and they are suitable for global motion estimation. by using background area most of the computations for calculation of global motion...
In this paper, a fast algorithm for digital image stabilization is proposed that use standard division properties and motion prediction to reduce the computational cost of block matching algorithm (BMA) for motion estimation. In most cases global motions have the repeating behavior, such as car, ship, and etc. In proposed method previous global motion vectors as saved (all previous vectors before...
In this paper a new method for motion estimation based on block matching, is proposed. This new method which is a combination of TSS and Cross search algorithm is used to estimate the local motions of an image for image stabilization. In the proposed method, instead of original image, bit-plane image is used to increase the speed of processing. Moreover, for global motion estimation a fuzzy-based...
