LI, Zhi  e  GOVENDER, P.. Development of an intelligent recognition and sorting system. S. Afr. J. Ind. Eng. [online]. 2012, vol.23, n.1, pp.226-236. ISSN 2224-7890.

This paper presents the design of an intelligent recognition and sorting system. Intelligence is included in the system by using a multilayer feed-forward artificial neural network (ANN) for image recognition. Full duplex Bluetooth communication is used between the intelligent system and a robot-control computer. Image compression and principal component analysis (PCA) reduce the dimensionality of the data, and only the salient feature vectors of an image are used for image recognition. A control signal guides a robot arm to place an object into an allocated space. The system is relatively immune to noise, and can generalise when faced with missing data.
