  • Publication number: 20230295751
    Abstract: The invention discloses a biosensor chip and a COVID-19 test kit. The COVID-19 test kit includes a biosensor chip, rolling circle amplification (RCA) primers, RCA padlock probes, and ssDNA conjugated nanoparticles (i.e., ssDNA-NPs probe). In this invention, the surface of the biosensor chip is modified with functional polymers; subsequently, detection ligands are grafted on the modified sensor chip surface to capture the targets. The developed biosensor chip achieves rapid and ultra-sensitive on-site detection of COVID-19 infections. In addition, a signal amplification method is employed using RCA products hybridized ssDNA-NPs probes (i.e., RCA-NPs) complex to amplify the detection signal and to improve the detection sensitivity.

  • Patent number: 10019622
    Abstract: The subject matter described herein relates to face alignment via shape regression. A method, computer storage medium, and system are provided. In one embodiment, the method comprises receiving an image including a face; and performing shape regression to estimate a facial shape in the image. For each stage in the shape regression, a local feature is extracted from a local region around each facial landmark in the image independently; and a joint projection is performed based on local features of multiple facial landmarks to predict a facial shape increment. Then, a facial shape of a current stage is generated based on the predicted facial shape increment and a facial shape of a previous stage.

  • Publication number: 20140341443
    Abstract: This disclosure describes a system for jointly modeling images for use in performing facial recognition. A facial recognition system may jointly model a first image and a second image using a face prior to generate a joint distribution. Conditional joint probabilities are determined based on the joint distribution. A log likelihood ratio of the first image and the second image are calculated based on the conditional joint probabilities and the subject of the first image and the second image are verified as the same person or as different people based on results of the log likelihood ratio.

  • Publication number: 20140185924
    Abstract: A two-level boosted regression function is learned using shape-indexed image features and correlation-based feature selection. The regression function is learned by explicitly minimizing the alignment errors over the training data. Image features are indexed based on a previous shape estimate, and features are selected based on correlation to a random projection. The learned regression function enforces non-parametric shape constraint.
