Image processing method and image processing apparatus

摘要

An image processing method and image processing apparatus for removing noise from an image. The image processing method includes: dividing an input image into a high frequency component and a low frequency component; removing noise from the high frequency component; and combining the low frequency component and the high frequency component from which noise is removed to form an output image. Accordingly, an image in which edge components are well preserved and a degree of color noise is reduced may be generated not only in a general environment but also in a low light level and highly sensitive environment having strong noise.

主权项

1. An image processing method comprising:
dividing using a processor an input image into low frequency components from which noise is removed and high frequency components; removing noise from the high frequency components; and combining the low frequency components and the high frequency components from which noise is removed to form an output image, wherein the dividing of the input image comprises:
obtaining the low frequency components from which noise is removed, from the input image;obtaining the high frequency components by calculating a difference between the input image and the low frequency components.
