Abstract: Aiming at the problems of large noise and low contrast for Kinect infrared images,an enhancement method was proposed for the Kinect infrared scene through analyzing the characteristics.Firstly,the infrared image contrast was enhanced by the OCTMalgorithm.Secondly,combined with the features of frequency domain for the Kinect infra-red scene,the noise frequency band was found.Finally,in order to get rid of noise and preserve edge details of the in-frared scene image,the images were enhanced with the band stop filter and bilateral filter.In order to prove the effec-tiveness and the practicability of the proposed method,the experiments of different infrared scenes were carried out, and multiple sets of real scenes were tested from subjective aspect and objective aspect.Experiments and the test re-sults show that the proposed method is very effective to enhance Kinect infrared scenes.
