Low Complexity FPGA Implementation of Emotion Detection for Autistic Children

摘要: Many autistic children have impairment in understanding other people's emotions which hinder their interpersonal communication. A real-time portable emotion detection system will aid such to interact with the external world easily by them understand facial during face In this paper we propose a low complexity detector using principal component analysis. The Eigen values are obtained power-deflation iteration method and proposed architecture optimizes calculation only required number of selective called as range rather than finding all vectors. recognizer is implemented on Virtex 7 XC7VX330T FFG1761-3 FPGA. We achieved 82.3 % accuracy for wordlength 8 bits.
