Problems solved by technology

Although this method is simple and does not require a large number of image calculations, this recognition method is extremely susceptible to the influence of different background light sources and environmental shadows, causing errors in the recognition results. Therefore, it is necessary to correct the color temperature and color difference, and the process is quite complicated.

Embodiment Construction

[0017] Please refer to figure 1 , figure 1 It is a block diagram of the first embodiment of the image recognition system of the present invention. In the figure, the image recognition system 1 includes an image extraction unit 11 , a processing module 12 , a storage unit 13 and a recognition module 14 .

[0018] Image extraction unit 11 can carry out image extraction operation to selected place, obtains first image at first time, obtains second image at second time, and image extraction unit can be gray level charge-coupled device (Gray level CCD) or other A camera device with a camera function.

[0019] The processing module 12 is connected to the image extraction unit 11, and processes the first image and the second image, and skeletonizes the first image and the second image, converts it into a first skeletonized image and a second skeletonized image, to obtain the first contour feature of the first skeletonized image and the second contour feature of the second skeleton...

Abstract

The invention discloses an image identification system and an image identification method. The system comprises an image extraction unit, a processing module, a storage unit and an identification module. The image extraction unit performs image extraction operation at a selected position; the processing module is connected with the image extraction unit, processes the images extracted by the image extraction unit by skeletonization, and acquires the outline characteristics of the skeletonized images; the storage unit is connected with the processing module, and stores the outline characteristics of the skeletonized images; and the identification module is connected with the storage unit, and compares the outline characteristics of the skeletonized images acquired at different time to identify whether the images acquired at different time are matched.

Description

technical field [0001] The present invention relates to an image recognition system and its method, in particular to an image recognition system and its method for recognizing images with a correlation analysis method. Background technique [0002] At present, according to the existing real-time image recognition technology, the digital image obtained by the camera and the image extraction interface is mainly used, and then the relevant recognition technology is used to judge whether there is a difference between different digital images, and to make a corresponding response according to the obtained difference value. [0003] An image recognition method disclosed in U.S. Patent No. 5,534,917 uses an AND operator to perform image recognition, mainly using a pattern in an area as a reference value and storing it in a storage unit, and then using a camera to perform image recognition. Images are continuously extracted for recognition at different times, and compared one by one...
