Background:

Traditional level set models struggle with weak boundaries and noise in target images.
Existing methods lack robustness and accuracy in complex image segmentation tasks.

Purpose of the Study:

To enhance image segmentation accuracy and robustness.
To improve edge contour extraction and noise reduction in target images.
To develop an improved level set model addressing limitations of traditional methods.

Main Methods:

Introduced a no-weight initialization level set model.
Integrated bilateral filters for noise reduction.
Utilized implicit surface level sets for object extraction.

Main Results:

The improved method demonstrated more accurate edge contour extraction compared to traditional non-reinitialized level set models.
Achieved superior noise reduction effects on the original target image.
Showcased a more intuitive and clear object extraction process.

Conclusions:

The proposed no-weight initialization level set model with bilateral filters offers significant improvements in image segmentation.
This enhanced approach provides better accuracy, robustness, and efficiency for target image analysis.
The algorithm effectively addresses the limitations of traditional level set models in handling noisy images with weak boundaries.
