Galaxy surface photometry [PDF]
Open Astronomy, 1999 We describe galaxy surface photometry based on fitting ellipses to the isophotes of the galaxies. Example galaxies with different isophotal shapes are used to illustrate the process, including how the deviations from elliptical isophotes are quantified ...

AN IMPROVED PHOTOCLINOMETRY TECHNIQUE FOR SURFACE RELIEF RETRIEVAL FROM IMAGES: ERROR LEVELS FOR HEIGHT AND SLOPE ESTIMATES [PDF]
Radio Physics and Radio Astronomy, 2023 Subject and Purpose. Computer simulation methods are used for investigating the errors that arise in the course of retrieval, by means of an improved photoclinometry technique, of planetary surface reliefs from sets of their photo images.

Theoretical formulation and experimental validation of brightness evaluation using digital cameras
Results in Optics, 2021 In this study, we formulated the brightness relation of two digital photos captured by a single digital camera and verified it experimentally. The experimental results suggested that the used zoom lens has an intrinsic error, thereby making accurate ...
