Latest Patents

One of Liu's latest patents is titled "Entrance detection from street-level imagery." This invention involves an architecture that detects entrances on building facades. In the first stage, scene geometry is utilized to reduce a multi-dimensional problem to a one-dimensional (1D) problem. Entrance hypotheses are generated by considering pairs of locations along lines with strong gradients in the transverse direction. The second stage explores a rich set of discriminative image features for entrances, focusing on properties such as symmetry and color consistency. Classifiers, such as random forests, are employed for automatic feature selection and entrance classification. Additionally, a joint model is formulated in three dimensions (3D) for entrances on a given facade, allowing for the systematic exploitation of physical constraints between different entrances to prune false positives and select an optimum set of entrances.

Another notable patent is related to an "Image processing for vehicle collision avoidance system." This collision warning system determines the probabilities of potential collisions between a vehicle and other objects. Sensors of a client device capture data, including motion data and image frames from a forward-facing view of the vehicle. The system determines cropped portions of the image frames and detects objects by processing these portions. It calculates the probability of a potential collision by tracking the motion of the object. If the probability exceeds a threshold value, the system notifies the driver of the potential collision.
