A single-scale (single-frequency) mathematical model of single and double end-stopped cells on the basis of Gabor filter responses was developed by Heitger et al. (1992 Vision Research 32 963-981). We developed an improved model by stabilising keypoint detection over neighbouring micro- scales.application/pdfengVisão computorizadaCórtex visual621.38Multi-scale keypoint hierarchy for Focus-of-Attention and object detectionjournal article
