Abstract
Disclosed is an image processing method including: generating an initial denoised image with a reduced noise while preserving an edge in an input image; controlling an iterative operation performed based on energy defined in advance based on an initial residual component calculated from the input image and the initial denoised image; and separating the initial denoised image to a skeleton component and a residual component by the controlled iterative operation to generate the skeleton component as an output image.

An image processing method comprising:
- generating an initial denoised image with a reduced noise while preserving an edge in an input image;
- controlling an iterative operation performed based on energy defined in advance based on an initial residual component calculated from the input image and the initial denoised image;
- and
- separating the initial denoised image to a skeleton component and a residual component by the controlled iterative operation to generate the skeleton component as an output image.
An image processing device comprising:
- an initial denoised image generation unit generating an initial denoised image by a noise removal method for storing an edge component in an input image;
- a skeleton component/residual component separation unit separating the initial denoised image to a skeleton component and a residual component by an iterative operation based on energy defined in advance and generating the skeleton component as an output image;
- and
- a control unit controlling the iterative operation based on the initial residual component.
