Facial expression recognition: feature based approaches to deep learning techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2020)Facial expression recognition (FER) is a problem of pattern recognition that invites the attention of computer vision researchers for the last three decades. However, the problem is still alive due to challenges such as - ... -
Locality preserving projection: a study and applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)Locality Preserving Projection (LPP) is a recently proposed approach for dimensionality reduction that preserves the neighbourhood information and obtains a subspace that best detects the essential data manifold structure. ... -
Sparse representation and fisher discriminant criterion based dimensionality reduction for face recognition
(2020)Dimensionality Reduction(DR) is a very popular topic in the field of pattern recognition. Generally, Practical applications like face recognition, object classification, and text categorization include high dimensional ... -
Variants of orthogonal neighborhood preserving projections for image recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)With the increase in the resolution of image capturing sensors and data storagecapacity, a huge increase in image data is seen in past decades. This informationupsurge has created a huge challenge for machines to perform ...
