2 code implementations22 Apr 2019 Hafiz Imtiaz, Jafar Mohammadi, Anand D. Sarwate

CAPE can be used in conjunction with the functional mechanism for statistical and machine learning optimization problems.

A Face Recognition Scheme using Wavelet Based Dominant Features

no code implementations7 Oct 2011 Hafiz Imtiaz, Shaikh Anowarul Fattah

In this paper, a multi-resolution feature extraction algorithm for face recognition is proposed based on two-dimensional discrete wavelet transform (2D-DWT), which efficiently exploits the local spatial variations in a face image.
