Latest Patents
One of Yanxi Liu's latest patents focuses on an architecture that detects entrances on building facades. In the initial stage, scene geometry is exploited, reducing the multi-dimensional problem to a one-dimensional (1D) problem. Entrance hypotheses are generated by considering pairs of locations along lines that exhibit strong gradients in the transverse direction. In the subsequent stage, a rich set of discriminative image features for entrances is explored according to constructed designs, specifically focusing on properties such as symmetry and color consistency. Classifiers, such as random forests, are utilized to perform automatic feature selection and entrance classification. In another stage, a joint model is formulated in three dimensions (3D) for entrances on a given facade. This model enables the exploitation of physical constraints between different entrances on the same facade in a systematic manner to prune false positives, thereby selecting an optimum set of entrances on a given facade.
