20090074071 | Apparatus and Method for Image Processing and Computer Program - An image processing apparatus includes the following elements. A local motion vector estimation unit estimates a local motion vector associated with each of blocks, serving as segments of an image frame constituting a moving image. A block weight calculation unit calculates a block weight as an index of the reliability of a local motion vector for each block. A global motion vector estimation unit receives the local motion vectors and the weights to estimate a global motion vector as a motion vector common to the blocks in the frame. The global motion vector estimation unit calculates, as a cost, the sum of the products of the differences between the local motion vectors associated with the respective blocks and the global motion vector and the block weights assigned to the respective blocks subjected to difference calculation and calculates parameters of the global motion vector which minimize the cost. | 03-19-2009 |
