Biochip image analysis system and method thereof

A biochip image analysis system comprising:

• an image storage unit for storing information on various types of images including an original image of a biochip including a set of genes extracted from samples of an experimental group and a control group, each tagged by fluorescent dyes of different colors;
• an image converter for converting the original image stored in the image storage unit into a test image, generating an overlapped image and a color image from the test image, and storing the respective images in the image storage unit;
• an edge detector for separating spots of the test image stored in the image storage unit into segments and detecting edges from a spot area and a background area so as to measure expression degrees of respective genes;
• a blob detector for detecting blobs from the spot area and the background area detected by the edge detector to generate a blob template;
• a blob remover for using the blob template generated by the blob detector to generate a spot template from which the blobs are removed and a background template;
• a data processor for calculating statistical data and correcting intensity on the basis of the spot template and the background template generated by the blob remover;
• and
• a data storage unit for storing the statistical data output by the data processor.
