Considerations about saliency map from Wide Angle Fovea image

Abstract

Wide Angle Fovea (WAF) sensor acquires images having both high resolution and wide angle simultaneously. Such an image is quite applicable for multi-purpose use of the single vision sensor. When the WAF sensor is equipped on a planetary exploring rover, it influences intuitively to the basic design and model of the rover which needs to be autonomous strongly. In this paper, the authors pay attention to difference between the saliency maps generated from the WAF image and the pinhole lens image. Thus, we compared and discussed the performance of our proposed object detection method between the WAF lens and the pinhole lens by taking into consideration characteristcs of the WAF image, i.e., non-uniform resolution throughout the entire field of view (FOV) and higher distortion in more peripheral FOV.
