Abstract

The invention discloses a salient object detection method based on image layering technology, which includes collecting the pixel value of each pixel in the background image; calculating the distance sum between it and other pixels for each pixel; and performing the distance sum of each pixel Convert the salient feature value of the pixel, and obtain the feature image according to the salient feature value of each pixel; record the maximum and minimum values ​​of all the salient feature values, calculate the difference between the maximum value and the minimum value, and map the feature image to within the numerical range; map the background image to the numerical range by corresponding pixel values ​​and saliency eigenvalues ​​to obtain the first stretched image; subtract the first stretched image from the feature image to obtain a sub-background image; map the sub-background image to Obtain the second stretched image in the numerical range; subtract the feature image from the second stretched image to obtain the target image. The invention also discloses an object detection system based on the above method, which includes a collection module, an image processing module, a calculation module and an output module.

Description

technical field [0001] The invention relates to the field of image layering technology detection, in particular to a method and system for detecting a salient object based on image layering technology. Background technique [0002] At present, for target object detection in complex environmental backgrounds, it is often easily affected by background information. For example, when the vehicle target is detected on the road, the sun casts a huge shadow from the trees on both sides of the road on a sunny day, and the vehicle happens to be in the shadow. At this time, it will be found that the shadow is more prominent on the image, and the vehicle is prominent in a local area inside the shadow. Therefore, if you want to detect the vehicle from the image, you can first separate the shadow, and then separate the vehicle from the shadow. This is the so-called "image layering". [0003] In general, if the target object exists in the background image but it is not easy to separate ...
