Using image signatures for place recognition
نویسنده
چکیده
This paper describes and evaluates an image-based place recognition method for mobile robots based on matching image signatures. The method represents an image as a set of arrays of coarse-scale measurements over subimages. We describe several diierent measurement functions we devised, and show how they can be used conjunctively to improve recognition accuracy. Experimental results show that this method enables accurate place recognition, comparable to recent results for localization using occupancy grids, and also to recent results for image-based ngerprint recognition.

Use of the Shearlet Transform and Transfer Learning in Offline Handwritten Signature Verification and Recognition
Despite the growing growth of technology, handwritten signature has been selected as the first option between biometrics by users. In this paper, a new methodology for offline handwritten signature verification and recognition based on the Shearlet transform and transfer learning is proposed. Since, a large percentage of handwritten signatures are composed of curves and the performance of a sig...

متن کاملIdentity authentication using improved online signature verification method
We present a system for online handwritten signature verification, approaching the problem as a two-class pattern recognition problem. A test signature s authenticity is established by first aligning it with each reference signature for the claimed user, using dynamic time warping. The distances of the test signature to the nearest, farthest and template reference signatures are normalized by t...
