Wavelet-based multifractal analysis of laser biopsy imagery
Jaidip Jagtap, Sayantan Ghosh, Prasanta K. Panigrahi +1
In this work, we report a wavelet based multi-fractal study of images of dysplastic and neoplastic HE- stained human cervical tissues captured in the transmission mode when illumin…
Differing self-similarity in light scattering spectra: A potential tool for pre-cancer detection
Sayantan Ghosh, Jalpa Soni, Harsh Purwar +4
The fluctuations in the elastic light scattering spectra of normal and dysplastic human cervical tissues analyzed through wavelet transform based techniques reveal clear signatures…
Probing Tissue Multifractality Using Wavelet based Multifractal Detrended Fluctuation Analysis: Applications in Precancer Detection
Jalpa Soni, Gregor P. Jose, Sayantan Ghosh +4
The refractive index fluctuations in the connective tissue layer (stroma) of human cervical tissues having different grades of precancers (dysplasia) was quantified using a wavelet…
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…
