Image processing method, apparatus, and system

An image processing method comprising:

• analyzing an original X-ray image after receiving it;
• performing a multi-scale transform on the original X-ray image based on the analysis result to separate it into frequency components;
• extracting and normalizing tissue region data based on a residual term corresponding to a low-frequency band X-ray image among the separated images;
• reconstructing the X-ray image based on the residual term that has undergone tissue normalization;
• and
• tone mapping and outputting the reconstructed X-ray image.

An image processing system comprising:

• an image acquisition device configured to acquire an X-ray image of a human body;
• a display;
• and
• an image processing device including:
• an image analysis module configured to analyze an original X-ray image;
• a transformation module configured to perform a multi-scale transform on the original X-ray image based on the result of the analysis and to separate the image into frequency components;
• a tissue processing module configured to extract and normalize tissue region data based on a residual term corresponding to a low-frequency band X-ray image among the separated X-ray images;
• an inverse transformation module configured to reconstruct the X-ray image based on the residual term that has undergone tissue normalization;
• and
• a control module configured to perform tone mapping and output control of the reconstructed X-ray image.
