However,it is reported that there is some noise called “Flicker Artifact”in the decoded image of Motion JPEG 2000. In video sequence,this noise is visually detected as large flicker deterioration to change Luminance value. In this paper,we study the method of flicker reduction in Motion JPEG 2000. In proposal method,we distinguishes between static and moving region in decoded image using threshold process and uses forward and backward frames.
