Query: RetinotopicNet: An Iterative Attention Mechanism Using Local Descriptors
  with Global Context   Convolutional Neural Networks (CNNs) were the driving force behind many
advancements in Computer Vision research in recent years. This progress has
spawned many practical applications and we see an increased need to efficiently
move CNNs to embedded systems today. However traditional CNNs lack the property
of scale and rotation invariance: two of the most frequently encountered
transformations in natural images. As a consequence CNNs have to learn
different features for same objects at different scales. This redundancy is the
main reason why CNNs need to be very deep in order to achieve the desired
accuracy. In this paper we develop an efficient solution by reproducing how
nature has solved the problem in the human brain. To this end we let our CNN
operate on small patches extracted using the log-polar transform, which is
known to be scale and rotation equivariant. Patches extracted in this way have
the nice property of magnifying the central field and compressing the
periphery. Hence we obtain local descriptors with global context information.
However the processing of a single patch is usually not sufficient to achieve
high accuracies in e.g. classification tasks. We therefore successively jump to
several different locations, called saccades, thus building an understanding of
the whole image. Since log-polar patches contain global context information, we
can efficiently calculate following saccades using only the small patches.
Saccades efficiently compensate for the lack of translation equivariance of the
log-polar transform.
