Background:

Molecular image segmentation is challenging due to low signal-to-noise ratios.
Existing methods struggle with noise and intensity variations.
Accurate segmentation is crucial for molecular image analysis.

Purpose of the Study:

To propose a novel two-dimensional fuzzy C-means (2DFCM) algorithm for robust molecular image segmentation.
To improve segmentation accuracy in the presence of noise and intensity variations.
To enhance the analysis of low signal-to-noise molecular images.

Main Methods:

A three-stage 2DFCM algorithm was developed.
Stage 1: Noise suppression using Gaussian filter and anisotropic diffusion.
Stage 2: Texture energy characterization with Gabor wavelets.
Stage 3: Integration of spatial constraints from denoised data and textural information into fuzzy clustering.

Main Results:

The 2DFCM algorithm effectively incorporates intensity and textural information.
Satisfactory segmentation results were achieved for noisy images with intensity variations.
Achieved 0.96 +/- 0.03 segmentation accuracy on synthetic images.
Demonstrated effectiveness on a real molecular image.

Conclusions:

The proposed 2DFCM algorithm offers a significant improvement for molecular image segmentation.
It robustly handles noise and intensity variations, crucial for low signal-to-noise images.
The method enhances the reliability of molecular image analysis.
