Comparison of Boundary Mapping Efficiency of Gradient Vector Flow Active Contours and their Variants on Chromosome Spread Images

A. Prabhu Britto and G. Ravindran
This study compares the boundary mapping efficiency of curve evolution method on chromosome spread images. The curve evolution methods chosen for comparison gradient vector flow active contours, generalized gradient vector flow active contours, discrete cosine transform based gradient vector flow active contours and discrete cosine transform based generalized gradient vector flow active contours. Chromosome spread images were characterized by chromosome images with variable shape and image properties. Experimental results showed that gradient vector flow active contours and its variants were successful boundary mapping tools for chromosome spread images. The result of this comparison was expected to yield a very efficient boundary mapping scheme for boundary mapping chromosome spread images.
