Histogram of Oriented Gradient Based Gist Feature for Building Recognition

Table 3

Mean recognition accuracy of Siagian & Itti’s gist + PCA and HOG-gist + PCA. The numbers in parentheses indicate the corresponding feature dimensions which give the best results after dimensionality reduction.

Siagian & Itti’s gist + PCA	81.82 (54)	82.33 (46)	83.10 (35)	84.62 (54)	85.25 (71)	87.40 (77)	90.17 (73)
SM-gist + PCA	81.96 (42)	85.34 (29)	87.48 (31)	89.30 (62)	90.03 (66)	91.82 (69)	92.28 (72)
