    摘要: Image concealment video conference allows the user to conceal their image with an overlay image that will be shown in real-time to a peer during video conference. The real-time video concealment processes an image in a video stream, where the video stream is communicated from one video conference unit to a second video conference unit over a communication network. The real-time concealment is performed by first determining the prominent biometric features of the users image to recognize nodal points on a human face. The system then modifies the users image using a second image, so that at least one of the nodal points in the users image is covered by the second image. This modified image is then transmitted in real time to a peer in a video conference session.

    摘要: An apparatus and method for human activity and facial expression modeling and recognition are based on feature extraction techniques from time sequential images. The human activity modeling includes determining principal components of depth and/or binary shape images of human activities extracted from video clips. Independent Component Analysis (ICA) representations are determined based on the principal components. Features are determined through Linear Discriminant Analysis (LDA) based on the ICA representations. A codebook is determined using vector quantization. Observation symbol sequences in the video clips are determined. And human activities are learned using the Hidden Markov Model (HMM) based on status transition and an observation matrix.
