Abstract EN
Noises and artifacts are introduced to medical images due to acquisition techniques and systems.
This interference leads to low contrast and distortion in images, which not only impacts the effectiveness of the medical image but also seriously affects the clinical diagnoses.
This paper proposes an algorithm for medical image enhancement based on the nonsubsampled contourlet transform (NSCT), which combines adaptive threshold and an improved fuzzy set.
First, the original image is decomposed into the NSCT domain with a low-frequency subband and several high-frequency subbands.
Then, a linear transformation is adopted for the coefficients of the low-frequency component.
An adaptive threshold method is used for the removal of high-frequency image noise.
Finally, the improved fuzzy set is used to enhance the global contrast and the Laplace operator is used to enhance the details of the medical images.
Experiments and simulation results show that the proposed method is superior to existing methods of image noise removal, improves the contrast of the image significantly, and obtains a better visual effect.
