LSB Based Non Blind Predictive Edge Adaptive Image Steganography
Soumendu Chakraborty, Anand Singh Jalal, Charul Bhatnagar
Image steganography is the art of hiding secret message in grayscale or color images. Easy detection of secret message for any state-of-art image steganography can break the stego…
Local Directional Gradient Pattern: A Local Descriptor for Face Recognition
Soumendu Chakraborty, Satish Kumar Singh, Pavan Chakraborty
In this paper a local pattern descriptor in high order derivative space is proposed for face recognition. The proposed local directional gradient pattern (LDGP) is a 1D local micro…
Local Quadruple Pattern: A Novel Descriptor for Facial Image Recognition and Retrieval
Soumendu Chakraborty, Satish Kumar Singh, Pavan Chakraborty
In this paper a novel hand crafted local quadruple pattern (LQPAT) is proposed for facial image recognition and retrieval. Most of the existing hand-crafted descriptors encodes onl…
Cascaded Asymmetric Local Pattern: A Novel Descriptor for Unconstrained Facial Image Recognition and Retrieval
Soumendu Chakraborty, Satish Kumar Singh, Pavan Chakraborty
Feature description is one of the most frequently studied areas in the expert systems and machine learning. Effective encoding of the images is an essential requirement for accurat…
Centre Symmetric Quadruple Pattern: A Novel Descriptor for Facial Image Recognition and Retrieval
Soumendu Chakraborty, Satish Kumar Singh, Pavan Chakraborty
Facial features are defined as the local relationships that exist amongst the pixels of a facial image. Hand-crafted descriptors identify the relationships of the pixels in the loc…
Local Gradient Hexa Pattern: A Descriptor for Face Recognition and Retrieval
Soumendu Chakraborty, Satish Kumar Singh, Pavan Chakraborty
Local descriptors used in face recognition are robust in a sense that these descriptors perform well in varying pose, illumination and lighting conditions. Accuracy of these descri…
R-Theta Local Neighborhood Pattern for Unconstrained Facial Image Recognition and Retrieval
Soumendu Chakraborty, Satish Kumar Singh, Pavan Chakraborty
In this paper R-Theta Local Neighborhood Pattern (RTLNP) is proposed for facial image retrieval. RTLNP exploits relationships amongst the pixels in local neighborhood of the refere…
A Novel Local Binary Pattern Based Blind Feature Image Steganography
Soumendu Chakraborty, Anand Singh Jalal
Steganography methods in general terms tend to embed more and more secret bits in the cover images. Most of these methods are designed to embed secret information in such a way tha…
Facial Biometric System for Recognition using Extended LGHP Algorithm on Raspberry Pi
Soumendu Chakraborty, Satish Kumar Singh, Kush Kumar
In todays world, where the need for security is paramount and biometric access control systems are gaining mass acceptance due to their increased reliability, research in this area…
Color Channel Perturbation Attacks for Fooling Convolutional Neural Networks and A Defense Against Such Attacks
Jayendra Kantipudi, Shiv Ram Dubey, Soumendu Chakraborty

diffGrad: An Optimization Method for Convolutional Neural Networks
Shiv Ram Dubey, Soumendu Chakraborty, Swalpa Kumar Roy +3
Stochastic Gradient Decent (SGD) is one of the core techniques behind the success of deep neural networks. The gradient provides information on the direction in which a function ha…
Average Biased ReLU Based CNN Descriptor for Improved Face Retrieval
Shiv Ram Dubey, Soumendu Chakraborty
The convolutional neural networks (CNN), including AlexNet, GoogleNet, VGGNet, etc. extract features for many computer vision problems which are very discriminative. The trained CN…
Secret Image Sharing Using Grayscale Payload Decomposition and Irreversible Image Steganography
Soumendu Chakraborty, Anand Singh Jalal, Charul Bhatnagar
To provide an added security level most of the existing reversible as well as irreversible image steganography schemes emphasize on encrypting the secret image (payload) before emb…
An Efficient Bit Plane X-OR Algorithm for Irreversible Image Steganography
Soumendu Chakraborty, Anand Singh Jalal, Charul Bhatnagar
The science of hiding secret information in another message is known as Steganography; hence the presence of secret information is concealed. It is the method of hiding cognitive c…
