Abstract:With the development of face recognition technology, more and more research on how to improve the intelligent recognition technology of facial expression is also more and more. How to improve the accuracy and integrity of face recognition is the main need of the current development, and the application of computing and cloud computing to face recognition has solved this problem to a certain extent. Through the improved bacterial foraging algorithm, and then it is applied to the main component analysis algorithm to extract the basic characteristics of the image analysis. Through the above algorithm into the computer network cloud storage, cloud computing technology to achieve the application of face recognition. This article will through image analysis for the algorithm's function deployment, and spinning, the image using intelligent face recognition software, classification, work function test. The experimental results show that the cloud computing system can achieve higher accuracy and adaptability to the current face recognition and classification by using the cloud computing technology.
