<p>A method for image temporal and spatial resolution processing based on the code rate control is presented. The method includes: an encoder obtains a critical code rate based on the inputted video and the variation of target distributed code rate; comparing the critical code rate with a predetermined threshold, if the critical code rate is below the threshold, then the image resolution adapted to the said target distributed code rate is acquired by downsampling, otherwise the general encoding will be implemented; a decoder recovers the original resolution of the received image through upsampling and carries out smoothing.</p> |
