Method and system for initializing templates of moving objects

[0016] Hereinafter, embodiments of the present invention are described. It is worth noting that all the embodiments described hereinafter can be combined in any way, ie there is no limitation that some described embodiments cannot be combined with other embodiments.

[0017] exist Figure 1a In step S100, each image in the sequence is divided into blocks. Each tile may consist of 8x8 or 16x16 pixels, however, not only square tiles but also tiles of other shapes or tiles with another number of pixels are possible. Images may also be referred to as "frames" or "fields". These images are taken by, for example, a digital camera and stored pixel-wise in memory.

[0018] In step S102, blocks in which motion occurs between consecutive images of the sequence are identified. Such block motion can be detected by computing error criteria for possible block displacements. For example, a sum of absolute difference, a correlation product, or other methods may be used as a matching crite...
