Invariant object localization is one of the challenging tasks in computer vision research. In this paper we present a robust rotation and scale invariant object localization method. A local Gabor filter space is treated as core of this method. Image rotation and scaling operations were transformed into shift operations along the Gabor filter space dimensions. This property enables efficient scale and rotation estimation without segmentation. The used Gabor Filter can deal with complex input data. This feature is used to analyze color images by reducing the color space. The method was tested with two standardized image databases and our own image database. Besides a good quality in localizing rotated and scaled objects, the method has a strong robustness against variations of lightning conditions and 3D viewpoint changes.
