Embodiment Construction

[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...

Abstract

A method for tracking a moving object in a sequence of images is provided, comprising: partitioning each of said images of said sequence into blocks, identifying blocks which have moved between consecutive images of said sequence, grouping adjacent blocks, which have moved in a same direction by a same distance, into a first group of blocks, initializing an initial template for said moving object with said first group of blocks and tracking said template in said sequence of images. A corresponding system for tracking moving objects is presented as well.

Description

technical field [0001] The present invention relates to a method and system for initializing a moving object template and a corresponding computer program product. Background technique [0002] In image processing, template tracking is used, for example, to track faces in video or for satellite surveillance. Also, in forward-looking cameras in automotive applications, template tracking is used to track vehicle motion in front of the ego vehicle. These templates are usually initialized manually or by classification, which is feasible because in forward-looking applications, the viewing angle does not change. However, in side view applications or vehicle blind spot monitoring, the viewing angle changes and the usual classification cannot be done. Contents of the invention [0003] The object of the present invention is to provide an improved method and an improved system for initializing a moving object template. [0004] This object is achieved by methods, systems and co...
