“…Image pixels are the final output of the geophysical data acquisition and processing chain. Pixel-based methods (Kvamme 2006; Ogden et al 2010; Verdonck et al 2019) have produced significant results, resulting in a clearer depiction of structures that would otherwise be less visible in individual datasets. Nevertheless, several critical issues must be considered with such imagery.…”

“…Despite the great advances in speed and coverage that have come with modern sensor platforms [117][118][119], archaeological geophysics still often has to cope with undersampled data due to the small size of many archaeological features. Hence, it is important that the available data are of the best possible quality as their interpretation can otherwise be very difficult [120]. Many sources of noise cannot be reduced (e.g., inherent electronic instrument noise, soil noise) and it is important to minimize those contributions to noise that can be controlled, for example, due to the careful operation of instruments and best possible positioning.…”

“…Other computer‐assisted detection techniques aside from than the previous ones have been used in archaeological applications of GPR, such as template matching and object‐based image analysis (OBIA) (see, e.g. Verdonck, De Smedt, & Verhegge, 2019). For example, Verdonck (2016) designed a method based on template matching for the extraction of buried linear features from the data and used it to detect Roman wall foundations.…”

“…For example, Verdonck (2016) designed a method based on template matching for the extraction of buried linear features from the data and used it to detect Roman wall foundations. Later, Verdonck et al (2019) employed OBIA to extract features corresponding to Roman building foundations from GPR and fluxgate gradiometer data, and features corresponding to pits and ditches from fluxgate gradiometer and earth resistance data. Leckebush et al (2008) developed algorithms for feature detection from GPR data based on 3D regression techniques and applied them to model Roman walls and a water channel, and Linford and Linford (2017) used OBIA to identify circular pit‐type anomalies and linear anomalies associated with Roman structural remains from GPR and magnetic data.…”
