Abstract

In this paper, we propose a new detector descriptor for the visual salient points and use it for a monocular visual Simultaneous Localization and Mapping (visualSLAM) application. Because in SLAM, the landmarks should be indexed with distinctive features, we aim to build a detector descriptor insuring the invariance to the rotation and the scale. First, the detector starts filtering an image with a steerable filter set, extracts Harris corners from the convolved image, next it clusters these corners, then it calculates a resulting set of feature points. We show that the repeatability of the detector is higher that other detectors like SIFT, SURF, CENSURE and BRISC. In addition, we implement the descriptor using color attributes. We represent the color at the location of each feature point with a pyramid characterized with many levels of quantization, and we calculate the entropy at each level. We make a simulation of Visual SLAM with known correspondences using these features to prove their efficiency in the localization and the map management of the robot.
