Digitized archive of the Kodaikanal images: Representative results of solar cycle variation from sunspot area determination [PDF]
, 2012 Photographic images are valuable data resources for studying long term changes in the solar magnetic field and its influence on the Earth's climate and weather. We digitized more than 100 years of white light images stored in photographic plates and films that are available at Kodaikanal observatory starting from 1904.

A No-Reference Quality Assessment Method for Digital Human Head [PDF]
arXiv, 2023 In recent years, digital humans have been widely applied in augmented/virtual reality (A/VR), where viewers are allowed to freely observe and interact with the volumetric content. However, the digital humans may be degraded with various distortions during the procedure of generation and transmission.

Optimized Patterns for Digital Image Correlation [PDF]
, 2012 This work presents theoretical background on a novel class of strain sensor patterns. A combination of morphological image processing and Fourier analysis is used to characterize gray-scale images, according to specific criteria, and to synthesize patterns that score particularly well on these criteria.
