Latest Patents

One of Jifeng Dai's latest patents is titled "Feature Flow for Video Recognition." This invention includes various embodiments that provide a fast and accurate framework for video recognition. The method involves receiving a first frame captured by an imaging device and designating it as a key frame. It generates at least one feature map to identify features in the key frame and subsequently processes a second frame designated as the current frame. A flow estimation algorithm is applied to both frames to create a flow field that represents the transition from the key frame to the current frame. This innovative approach allows for the propagation of feature maps based on the flow field, effectively approximating the current locations of identified features.

Another notable patent is related to "Image Semantic Segmentation." In this implementation, feature maps are obtained by convoluting an input image using multiple layers of convolution filters. These feature maps capture semantic information for different regions of the image and are computed only once. The method extracts segment features from the convolutional feature maps, utilizing binary masks derived from candidate segments of the image. This process enables the determination of a semantic category for each pixel in the image based on the resulting segment features.
