1. A video stabilizing method, comprising the steps of: 1) capturing a low-spatial-resolution image I L t by a first camera for monitoring a panoramic area and a high-spatial-resolution image I H t by a second camera which is synchronous with the first camera for capturing an image of a moving target where I L t , I H t represent the low-spatial-resolution image and the high-spatial-resolution image at the t th time respectively; 2) determining a target region I L — tar t including the moving target in the low-spatial-resolution image I L t , and obtaining an output image I out t of the high-spatial-resolution image I H t corresponding to the target region I L — tar t ; 3) generating a registration model M LH t between the low-spatial-resolution image I L t and the high-spatial-resolution image I H t ; and 4) inpainting the output image I out t based on the registration model M LH t and the high-spatial-resolution image I H t to complete the output image I out t .
