Basic Image Features (BIFs) are a significant contribution by this group. Computation of BIFs consists in classifying each pixel of an image into one of seven categories depending on local structures and symmetries, creating a primal sketch of the input image. BIFs are computed efficiently based on the responses to a bank of Derivative-of-Gaussian (DtG) filters.
The computation of BIFs is controlled by a scale parameter (σ, the standard deviation of the DtG filters) and a threshold parameter (ε) dictating the fraction of an image that should be considered as 'flat' (i.e. without a particular structure).
BIFs can be used to encode compact representations of images (e.g. 7-bin histograms). The seven categories can be extended to 23 by quantization of the non-rotationally symetric features. Those 23 features are termed oriented Basic Image Features, or oBIFs.
Please visit the GitHub repository for implementations and examples of BIFs, oBIFs (oriented BIFs) and oBIF histograms (binned histograms of oBIFs).
BIFs and oBIFs have been employed for a wide variety of applications. Here you will find links to relevant papers ordered by the type of applications.
