Abstract

The invention relates to the field of intelligent visual recognition, in particular to a method, system and electronic device for setting an image change region detection threshold. This method obtains the first image before and after the scene change and the corresponding second image, and performs blurring processing to obtain the processed first blurred image and the second blurred image; The difference between the pixels is obtained as the first difference map; the first difference map is further optimized to obtain the second difference map, and the Otsu algorithm is used to process the second difference map to obtain the change area based on the first image and the second image detection threshold. Obtaining the threshold value through the above method can accurately and efficiently detect the image change area, prevent environmental interference from affecting the image change detection accuracy, and meet the use requirements of the contemporary intelligent container field. The image change area detection threshold setting system and its electronic device have the same beneficial effect as the above method.

Description

【Technical field】 [0001] The invention relates to the field of intelligent visual recognition, in particular to a method, system and electronic device for setting an image change area detection threshold. 【Background technique】 [0002] Now the new retail industry is gradually emerging, and unmanned containers have also been widely promoted. The unmanned containers currently on the market can identify the products for sale displayed on the container by obtaining real-time image information of the products for sale in the container, for example, by detecting the changes between the images of the products for sale taken at different times, knowing The sales status of the item for sale. Currently, the commonly used method for detecting image change regions is to set a threshold, and distinguish the pixel level of the image through the threshold, so as to realize the separation of the changing target product from the background. However, if the threshold is set too high, it wi...
