Abstract
An image processing apparatus and method are disclosed. The apparatus may include: a wavelet transform device for performing wavelet transform on an input image to decompose the input image into a plurality of levels of different scales, each level including a low frequency component and a plurality of high frequency components; a compensation template generating device for generating a compensation template for each level according to the plurality of high frequency components in the level, the compensation template reflecting combination feature of the plurality of high frequency components; a de-noising device for de-noising the low frequency component of each level and performing edge compensation on the low frequency component with the compensation template to acquire a compensated low frequency component; and a wavelet inverse transform device for performing inverse wavelet transform with the compensated low frequency component and the high frequency components of each level to acquire a de-noised image.
