Practical, Computation Efficient High-Order Neural Network for Rotation and Shift Invariant Pattern Recognition
In this paper, a modification for the high-order neural network (HONN) is presented. Third order
networks are considered for achieving translation, rotation and scale invariant pattern recognition. They require
however much storage and computation power for the task. The proposed modified HONN takes into account a
priori knowledge of the binary patterns that have to be learned, achieving significant gain in computation time and
memory requirements. This modification enables the efficient computation of HONNs for image fields of greater
that 100 × 100 pixels without any loss of pattern information
Modular Adaptive System Based on a Multi-Stage Neural Structure for Recognition of 2D Objects of Discontinuous Production
This is a presentation of a new system for invariant recognition of 2D
objects with overlapping classes, that can not be effectively recognized with
the traditional methods. The translation, scale and partial rotation invariant
contour object description is transformed in a DCT spectrum space. The obtained
frequency spectrums are decomposed into frequency bands in order to feed
different BPG neural nets (NNs). The NNs are structured in three stages -
filtering and full rotation invariance; partial recognition; general
classification. The designed multi-stage BPG Neural Structure shows very good
accuracy and flexibility when tested with 2D objects used in the discontinuous
production. The reached speed and the opportunuty for an easy restructuring and
reprogramming of the system makes it suitable for application in different
applied systems for real time work.Comment: www.ars-journal.co
Object Recognition
Vision-based object recognition tasks are very familiar in our everyday activities, such as driving our car in the correct lane. We do these tasks effortlessly in real-time. In the last decades, with the advancement of computer technology, researchers and application developers are trying to mimic the human's capability of visually recognising. Such capability will allow machine to free human from boring or dangerous jobs
