| Abstract(in English) | DNA micorarray is known as a method to obtain information of many different genes by one experiment. In order to effectively use this method, however. we need to automate the image processing part of the method. We describe an image processing algorithm for this purpose. A DNA micorarray image consists of a lot of spots regularly placed in a grid shape. The intensity of each spot corresponds to activeness of a specific gene. Therefore, the function of the image processing algorithm is to identify each spot and to measure its intensity. The algorithm first detects candidates of the spots and determines the angle and position of the grid formed by the spots. Then, it selects correct spots from the candidates using the information of the grid position. Next, the algorithm estimates the background levels of the image by intensity histograms and measure the intensity of each spot. |
