Apparatus and method for reducing motion compensation noise of image using wavelet transform

摘要

The present invention is blurred image by removing noise problems by predicting the movement of the video by using the wavelet transform. will or on the image of the motion-compensated noise reduction apparatus and method using a wavelet transform which can suppress the dragging of an image. Using the wavelet transform of the image motion compensated noise reduction device is a wavelet transform to produce a sub-image by filtering the input image portion, the sub-pictures to predict the motion of the previous and the current image of the low frequency sub-band of interest (ROI: region of interest) motion predictor generating an image, the sub-image noise high frequency subband images to selectively remove the noise according to said area of interest in the image and removing the noise is synthesized by removal of the sub-image of the includes a wavelet inverse transform to generate the output image. ; wavelet transform, motion estimation, noise attenuation curve, gegeo noise, the wavelet inverse
