Automatic face enhancement technique using sigmoid normalisation based on single scale Retinex algorithm
The identical faces look dissimilar due to the change of illumination and it leads to incorrect results in face detection. In general, The Retinex algorithm improves visual quality by attaining good dynamic range and colour constancy. This work, a single-...
Transient liveness factor an attempt towards identification of innate fingerprint under varying spoof sample
Fingerprint liveness detection works reasonably well when attacks are known. A 'constrained' design is biased to the taste of the researcher. Solutions appreciated initially, discarded later on based on issues of reproducibility and interoperability. ...
Face recognition using local binary pattern and Gabor-Kernel Fisher analysis
Face recognition technology is one of the everyday tasks in our daily life. But, recognising the correct face with high accuracy from large databases is a challenging task. To overcome this challenge, feature fusion of local binary pattern (LBP) with ...
Nature-inspired query optimisation models for medical information retrieval with relevance feedback
Medical information retrieval (MedIR) involves retrieving relevant medical-related information from a set of medical documents for a particular user query. As the volume of medical records grows, the challenging problem is determining those documents ...
Monitoring of environmental parameters using internet of things and analysis of correlation between the parameters in a DWC hydroponic technique
Internet of things (IoT) plays a major role in precision and sustainable agriculture system in urban farming. Hydroponic is one such modern technique where plant growth can be controlled and monitored with ease by integrating intelligence along with ...
On primes, semiprimes and their applications
The existence of hidden symmetries in the distribution of prime numbers and the open problems such as given a semiprime, how fast we can find its prime factors and all even integers that are adequately large could be realized as a sum of either two prime ...
An efficient data aggregation with optimal recharging in wireless rechargeable sensor networks
Energy consumption is optimised for transmission of packet in the clustering network there are base station selected to multiple mobile nodes covered under the particular distance range and limited distance to hit and elect the cluster group from the sink ...
