Efficient and robust image descriptor for GUI object classification Anastasia Dubrovina, Pavel Kisilev, Daniel Freedman, Sagi Schein, Ruth Bergman HP Laboratories HPL-2011-200 Keyword(s): GUI object classification; image descriptor Abstract: Graphical User Interface (GUI) object classification is essential for image-based software automation tools.The challenges posed by GUI object classification are significantly different from those in natural imageclassification. In this paper we present a novel image descriptor developed specifically for GUI objects; itis robust to various changes in the appearance of GUI objects, such as various screen resolution, "skin", aswell as various operating system related. We use this image descriptor with Support Vector Machineclassifier, and experimentally show the descriptor robustness to the above transformations, and its superiorperformance compared to existing image descriptors.
