Ringing artifacts arise near large edges in highly compressed JPEG2000 images. In this letter, a ringing artifact reduction scheme designed for low bit-rate JPEG2000 images is proposed. A local adaptive filter is adopted to process the received image in spatial domain and each wavelet subband. Meanwhile, a new method to estimate the variance of compression loss is put forward. The scheme can achieve both PSNR improvement and human perceptual enhancement in most cases. |
