Latest Patents

Peilei Dong's latest patents include a "Cross-media retrieval method based on deep semantic space." This method involves a feature generation stage and a semantic space learning stage. In the feature generation stage, a CNN visual feature vector and an LSTM language description vector of an image are generated by simulating a person's perception process for the image. Additionally, topic information about a text is explored using an LDA topic model, which helps in extracting an LDA text topic vector. The semantic space learning phase involves training a four-layer Multi-Sensory Fusion Deep Neural Network for images and a three-layer text semantic network for texts. Ultimately, this method significantly enhances the performance of cross-media retrieval.

Another patent is the "Method for detecting pedestrians in image by using Gaussian penalty." This method improves pedestrian detection performance, particularly for sheltered pedestrians in an image. It involves acquiring a training data set, a test data set, and pedestrian labels. The training data set is used to train a detection model, which screens initial pedestrian boundary boxes using a Gaussian penalty. This process helps in removing repeated boundary boxes of a single pedestrian while retaining those of sheltered pedestrians, thus achieving effective pedestrian detection.
