%description
Incorporates functions for image preprocessing, filtering and image
recognition. The package takes advantage of 'RcppArmadillo' to speed up
computationally intensive functions. The histogram of oriented gradients
descriptor is a modification of the 'findHOGFeatures' function of the
'SimpleCV' computer vision platform, the average_hash(), dhash() and
phash() functions are based on the 'ImageHash' python library. The Gabor
Feature Extraction functions are based on 'Matlab' code of the paper,
"CloudID: Trustworthy cloud-based and cross-enterprise biometric
identification" by M. Haghighat, S. Zonouz, M. Abdel-Mottaleb, Expert
Systems with Applications, vol. 42, no. 21, pp. 7905-7916, 2015,
<doi:10.1016/j.eswa.2015.06.025>. The 'SLIC' and 'SLICO' superpixel
algorithms were explained in detail in (i) "SLIC Superpixels Compared to
State-of-the-art Superpixel Methods", Radhakrishna Achanta, Appu Shaji,
Kevin Smith, Aurelien Lucchi, Pascal Fua, and Sabine Suesstrunk, IEEE
Transactions on Pattern Analysis and Machine Intelligence, vol. 34, num.

Superpixels", Radhakrishna Achanta, Appu Shaji, Kevin Smith, Aurelien
