Log-Spiral Keypoint: A Robust Approach toward Image Patch Matching

Figure 6

Average recall comparison of the three algorithms for five image groups. Each vertical bar in the plots corresponds to average recall value for each image group. (a) Comparison of the matching results obtained when BRISK perform the keypoint detection using the image pyramid consisting of 4 octave layers and (b) when the number of octave layer set to 0.
