Dna Image Segmentation – a Comparison of Edge Detection Techniques

Bioinformatics is a computer-assisted interface discipline dealing with the acquisition, storage, management, access and processing of molecular biology data. It is an interdisciplinary scientific tool without barriers among various disciplines of science like biology, mathematics, computer science and information technology. Bioinformatics has become an important part of many areas of biology. Bioinformatics tools aid in the comparison of genetic and genomic data and more generally in the understanding of evolutionary aspects of molecular biology. In structural biology, it aids in the simulation and modelling of DNA, RNA and Protein structures as well as molecular interactions. The most important feature of DNA is that it is usually composed of two polynucleotide chains twisted around each other in the form of a double helix. In this paper we have easily identified the complicated structure of DNA images for using several techniques of edge detection in image processing .we consider various well known Algorithms and metrics used in image processing applied to DNA images in this comparison .
