Embodiment Construction

[0026] Extracting images of foreground objects from images with complex backgrounds is a basic problem in many image processing application fields. Whether or not images of foreground objects can be better extracted will have a great impact on subsequent image processing applications, and even affect applications. of the final result. The present invention mainly realizes the extraction of images of foreground objects in images with complex backgrounds, and integrates the extracted images of foreground objects with the exterior images in the whole system, so as to realize that the foreground characters are here, and the characters in the photos taken are in different places Effect.

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] refer to figure 1 , the basic hardware system of the present invention comprises as follows: a frame 2 similar to a door frame is arranged on a relatively large ...

Abstract

The invention provides a foreground extraction method under a complicated background. An infrared lamp is used for polishing over foreground objects. Then, an infrared camera and a color camera are used for extracting images. The infrared camera obtains the images, the foreground objects are illuminated because of polishing of the infrared lamp. A certain threshold value is used for carrying out binarization processing over the infrared images so that a mask image which corresponds to the foreground objects can be digged out. The mask image is carried out fine adjustment up and down of the pixel positions so as to be consistent with the images acquired by the color camera. Finally, the mask image after the fine adjustment is used for completely extracting the foreground image and well keeping the edges of the foreground images. Great improvements on the accuracy of extracting the foreground are obvious.

Description

technical field [0001] The invention relates to a technology for extracting foreground object images from images with complex backgrounds, that is, to obtain the required images of specific foreground objects that are not blocked in the images collected by a camera. Background technique [0002] In the research and application of image processing, we are often only interested in certain parts of the image, and these parts of our interest are often called the foreground, that is, the foreground is generally a description of a specific area with unique properties in the image. It is necessary to extract these areas, that is, the foreground, and on this basis, it is possible to further analyze and utilize the foreground. Extracting images of foreground objects in images with complex backgrounds is a difficult problem of foreground extraction, because objects in complex backgrounds will affect the extraction of foreground objects, especially objects with changes in complex backg...
