In-pixel generation of gaussian pyramid images by block reusing in 3D-CMOS [PDF]
, 2012 This paper introduces an architecture of a switched-capacitor network for Gaussian pyramid generation. Gaussian pyramids are used in modern scale- and rotation-invariant feature detectors or in visual attention.

Automatic selection of correlated double sampling timing parameters
Journal of Astronomical Telescopes Instruments and Systems, 2019 Correlated double sampling (CDS) is a process used in many charge-coupled device readout systems to cancel the reset noise component that would otherwise dominate.

Spatially explicit density and its determinants for Asiatic lions in the Gir forests.
PLoS ONE, 2020 Asiatic lions (Panthera leo persica) are an icon of conservation success, yet their status is inferred from total counts that cannot account for detection bias and double counts. With an effort of 4,797 km in 725 km2 of western Gir Protected Area, India,
