Method and apparatus for finding and distinguish persons, animals or vehicles by means of automatic image monitoring digital or digitized images

摘要

A method for finding and distinguish persons, animals or vehicles by means of automatic image monitoring digital or digitized images, comprising the following method steps:a) determination of a static background image, comprising a subtraction of two images b (t_n), B (t_{n + 1}) at the point in time t_n and t_{n + 1}, the images b (t_n), B (t_{n + 1}) from the difference with a first threshold value s₁ only pixels are compared and larger than the threshold value s₁ the differential image can be taken into account and with a second threshold value s₂ is remachined,b) determination of the property of images of the original image b (t_n), the determined property images can be associated with one another, about the not to the static background image objects belonging to examine in more detail, wherein in a function of the linking of the object, in addition, the background image is associated with or, as the object is considered,c) repeating the process steps a) and b) at a later point in time, the two background determined and normalized added in order thus to a background image generation of adaptively to produce,d) determining a difference image..
