Multiscale periodicities in aerosol optical depth over India
S. Ramachandran, Sayantan Ghosh, Amit Verma +1
Aerosols exhibit periodic or cyclic variations depending on natural and anthropogenic sources over a region, which can get modulated by synoptic meteorological parameters such as w…
Characterizing and modeling cyclic behavior in non-stationary time series through multi-resolution analysis
Dilip P. Ahalpara, Amit Verma, Prasanta K. Panigrahi +1
A method based on wavelet transform and genetic programming is proposed for characterizing and modeling variations at multiple scales in non-stationary time series. The cyclic vari…
Locally Adaptive Block Thresholding Method with Continuity Constraint
S. Hemachander, Amit Verma, Siddharth Arora +1
We present an algorithm that enables one to perform locally adaptive block thresholding, while maintaining image continuity. Images are divided into sub-images based some standard…
Multilevel Thresholding for Image Segmentation through a Fast Statistical Recursive Algorithm
Siddharth Arora, Jayadev Acharya, Amit Verma +1
A novel algorithm is proposed for segmenting an image into multiple levels using its mean and variance. Starting from the extreme pixel values at both ends of the histogram plot, t…
