Building Extraction From RGB VHR Images Using Shifted Shadow Algorithm

A Framework for Automatic Building Detection from Low-Contrast Satellite Images

“…Nevertheless, other measurement criteria are well efficient than the Huang et al study (Table 4). Moreover, in studies [63,[65][66][67][68][69][70], f -score also depicts a good and acceptable achievement recall (completeness) values. Furthermore, methods used in [63,65,66,[68][69][70] also obtained acceptable standard precision values including this study.…”

“…Moreover, in studies [63,[65][66][67][68][69][70], f -score also depicts a good and acceptable achievement recall (completeness) values. Furthermore, methods used in [63,65,66,[68][69][70] also obtained acceptable standard precision values including this study. However, based on the insights of extant literature, we considered all measurement criterion values rather than f -score, precision and recall individually to extract building objects and found our method to be the more novel for extracting building objects from satellite images and can be treated as a best fit for extracting building objects from low-contrast satellite images.…”

“…Furthermore, while comparing measurement criteria among the listed studies from current and recent past in Table 4, the Li et al [68] study presents the lowest overall accuracy of detecting building objects i.e., 59.85%, while Chen et al [70] in their study have achieved the highest accuracy of detecting building objects, i.e., 89.8%. Moreover, methods used in [63][64][65][66][67]69] yielded between 70.1% to 84.66% accuracy. From the perspective insights of past literature, it is highlighted that, in an extraction task, the accuracy is a less considered measurement criterion than others [70].…”

“…Table 4 presents the experimental findings to distinguish this study with most recent and current studies. Table 4 depicts the quantitative stats to measure quality performance evaluation of the proposed method about the approaches used in the extant literature [63][64][65][66][67][68][69][70]. The results from the prior literature are compared on the basis of commonly used measurement criteria for precision, recall rate, and f -score.…”

“…Furthermore, the computation cost is also taken into consideration in the authors' proposed method, which consumes lesser computational time as compared to the already used methods, i.e., 13 s (approximately) ( Table 4). The computational time presented in Table 4 for past studies' methods [63,[65][66][67][68][69][70] required a lot of computational time. Finally, the quantitative assessment capability of the proposed method shows that the method carries significant potential to extract buildings from low-contrast satellite images and surpasses the accuracy statistics of previous methods used.…”
