PROBLEM TO BE SOLVED: To provide an affine immutable key point detector the processing speed of which is relatively high.SOLUTION: A key point detector 100 comprises: a filter decomposer 12 that dissolves a plurality of filters which is expressed by a finite number of continuous parameters into a plurality of unique filters; and an extreme searcher 14 that approximates a filter response value to any value of the continuous parameters using a linear sum filter response values of the unique filters and extracts the extreme approximated filter response values as key points.SELECTED DRAWING: Figure 1
