Multilayer Perceptron-Based Phenological and Radiometric Normalization for High-Resolution Satellite Imagery

Abstract: Radiometric normalization is an essential preprocessing step that must be performed to detect changes in multi-temporal satellite images and, in general, relative radiometric normalization is utilized. However, most relative radiometric normalization methods assume a linear relationship and they cannot take into account nonlinear properties, such as the distribution of the earth's surface or phenological differences that are caused by the growth of vegetation. Thus, this paper proposes a novel method that assu… Show more

“…Conventional image-fusion methods use only the pixel values of SAR and panchromatic images. However, in general, the gray level of single pixels is not informative; therefore, additional information other than the pixel values is necessary [38,39]. To ensure that abundant information is considered, this study uses texture information.…”

“…In general, RRN is classified into global statistical (GS) and radiometric control set sample (RCSS) methods [36,42]. The GS method uses the brightness value of all the pixels in the image [36,42], whereas the RCSS method uses the selected invariant features between images [8,39].…”

“…In general, RRN is classified into global statistical (GS) and radiometric control set sample (RCSS) methods [36,42]. The GS method uses the brightness value of all the pixels in the image [36,42], whereas the RCSS method uses the selected invariant features between images [8,39]. When the images exhibit similar radiometric characteristics, the GS method can rapidly and simply minimize the difference in brightness values between images [43,44].…”
