Currently there exists no application-independent or general theory of feature detection. In this work, a brightness induction wavelet model (BIWaM) is extended with the long-term aim of developing a principled model for generic local feature detection. This detector, the Feature Induction Wavelet Model (FIWaM), uses the same “featureness” measure for a range of local features such as blobs, bars and corners. FIWaM is a wavelet-based computational model that attempts to use the perceptual processes involved in visual brightness induction to enhance and detect these features. The model uses two center-surround mechanisms in sequence to detect features - a Gabor-like mother wavelet followed by an explicitly-defined center-surround region mechanism. These center-surround regions are feature-specific and introduce the only variation in the detection schema between features. Preliminary results have shown that this mechanism is effective in detecting features and achieves a repeatability performance in line with current state-of-the-art detection methods.
