In this work, different global appearance descriptors are evaluated to carry out the localization task, which is
a crucial skill for autonomous mobile robots. The unique information source used to solve this issue is an omnidirectional camera. Afterwards, the images captured are processed to obtain global appearance descriptors.
The position of the robots is estimated by comparing the descriptors contained in the visual model and the
descriptor calculated for the test image. The descriptors evaluated are based on (1) analytic methods (HOG
and gist) and (2) deep learning techniques (auto-encoders and Convolutional Neural Networks). The localization
is tested with a panoramic dataset which provides indoor environments under real operating conditions.
The results show that deep learning based descriptors can be also an interesting solution to carry out visual
