Intensity correction
NettetThe luminous intensity decreases rapidly with the increasing of emitting angle. The illumination intensity of different angles cannot be consistent, which leads to the decline of the reconstructed image quality. Consequently, the intensity correction of low-resolution raw images is consequently needed before the iterative phase retrieval process. NettetLight Detection and Ranging (LiDAR) data collected by mobile mapping systems (MMS) have been utilized to detect lane markings through intensity-based approaches. As LiDAR data continue to be used for lane marking extraction, greater emphasis is being placed on enhancing the utility of the intensity values. Typically, intensity …

Nettetcategory such as Gamma Intensity Correction (GC) [9] have been proposed recently with impressive performance improvement for illumination problem. Besides special algorithms are designed to overcome above difficulties, to obtain more face samples is another important way to improve the performance of face recognition [10]. NettetIntensity non-unifor-mity correction consists in determining u knowing v. This yields an underdetermined problem due to the fact that only vð~rÞ is known while both gð~rÞ and uð~rÞ have to be computed. Intensity non-uniformity has been studied by the com-munities involved in the acquisition and the processing of
NettetPurpose: Although acute bouts of exercise reportedly have beneficial effects on executive function, inactive people may find it difficult to start exercising. In this study, we focused on housework activities (HAs) that generate a sense of accomplishment and require a mild intensity of physical activity. Nettet8. jul. 2014 · This method estimates the parameters of customized range–intensity equations using a novel sample data collection design. Using the angle-of-incidence correction method, practical intensity...
NettetFlat-field correction (FFC) is a technique used to improve quality in digital imaging. It cancels the effects of image artifacts caused by variations in the pixel-to-pixel sensitivity of the detector and by distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.
