Abstract

The invention relates to the field of intelligent visual recognition, in particular to an image change area detection threshold setting method and system and an electronic device thereof. The method comprises the steps of obtaining a first image before and after scene change and a second image corresponding to the first image, and performing fuzzification processing on the first image and the second image to obtain a processed first blurred image and a processed second blurred image; Calculating a difference value between corresponding pixel points of the first blurred image and the second blurred image to obtain a first difference image; And further optimizing the first difference image to obtain a second difference image, and processing the second difference image by using an Otsu algorithm to obtain a threshold value detected based on a change area between the first image and the second image. According to the method, the image change area can be accurately and efficiently detectedby obtaining the threshold value, environmental interference is prevented from influencing the image change detection precision, and the use requirements of the field of contemporary intelligent containers are met. The image change area detection threshold setting system and the electronic device thereof have the same beneficial effects as the 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...
