Background:

Multiplex fluorescent in situ hybridization (M-FISH) is an advanced chromosome imaging technique.
M-FISH aids in detecting subtle chromosomal aberrations and simplifies image analysis for both human and computer inspection.

Purpose of the Study:

To present a novel method for segmenting and classifying M-FISH chromosome images.
To enhance the accuracy and efficiency of automated M-FISH image analysis.

Main Methods:

A novel method combining multichannel watershed transform for segmentation and a Bayes classifier for region classification.
The process involves gradient magnitude computation, watershed transform, region classification, and merging of similar regions.

Main Results:

The proposed method achieved an overall accuracy of 82.4% on a public chromosome image database.
It demonstrated superior results compared to existing methods with lower computational cost.
The combination of multichannel segmentation and region-based classification outperformed pixel-by-pixel approaches.

Conclusions:

The novel method offers improved accuracy and efficiency for M-FISH chromosome image analysis.
Region-based classification integrated with multichannel segmentation enhances overall classification performance.
This approach provides a more effective tool for genetic aberration detection.
