Paper Abstract

Sponsored by the National Aeronautical Space Association (NASA), the Synergetic Education and Research in Enabling NASA-centered Academic Development of Engineers and Space Scientists (SERENADES) Laboratory was established at California State University, Los Angeles (CSULA). An important on-going research activity in this lab is to develop an easy-to-use image analysis software with the capability of automated object detection to facilitate astronomical research. This paper presents the design and implementation of an automated astronomical image analyzer. The core of this software is the automated object detection algorithm developed in our previous research, which is capable of detecting objects in near galaxy images, including objects located within clouds. In addition to the functionality, human factor is considered in system design and tremendous efforts have been devoted to enhance the user friendliness. Instead of using command line or static menus, graphical methods are enabled in our software system to allow the user to directly manipulate the objects that he/she wants to investigate. Comprehensive tests are conducted by users with and without astronomical backgrounds. Compared to current software tools such as IRAF and Skyview, our developed software has the following advantages: 1) No pre-training is required; 2) The amount of human supervision is significantly reduced by automated object detection; 3) Batch processing capability is supported for fast operation; and 4) A high degree of human computer interaction is realized for better usability.
