Evaluation of Discrete Cosine Transform based Gradient Vector Flow Active Contours as an efficient tool for boundary mapping of Chromosome spread images
G. Ravindran · 2006
In this research, characterization of Discrete Cosine Transform (DCT) based Gradient Vector Flow (GVF) Active Contours as a n efficient boundary mapping technique for chromosome spread images is done. Statistical testing validates the experimental results of characterization. Investigations on a different dataset are carried out to validate the characterized parameters and the parameters are standardized. Further experiments are carried out to evaluate the validity of the standardization using another dataset. Error Quantification justified the successful standardization. It is hence established that DCT based GVF Active Contour is an efficient tool for boundary mapping of chromosome spread images.
