Method for preparing high-purity nano-sheet polyaniline

The present invention discloses a preparation method for a high-purity nanometer-polyaniline, belonging to the polyaniline preparation technology. The preparation method comprises: aniline methanol solution, ethanol solution, propanol solution or butanol solution with a concentration of 0.1 to 2.0 mol question mark L ^{-1 is mixed with carbinol solution, ethanol solution, propanol solution or butanol solution of organic acid doping agent with a concentration of0.05 to 1.0 mol question mark L -1 and are placed in a reactor. Then the reactor is added with carbinol solution, ethanol solution, propanol solution or butanol solution of oxidation initiator with a concentration of 0.1 to 1.0mol question mark L-1. The reaction temperature is 10 DEG C to 70 DEG C, and the reaction time is 12 to 72 hours. Polyaniline is generated through the reaction, which is then filtered and dried to get nanometer- polyaniline. The present invention has the advantage that the ...}

Method for tracking human skeleton motion in unmarked monocular video

The invention relates to a method for tracking human skeleton motion in an unmarked monocular video, which comprises the following steps: (1) pre-treating a video image to obtain a binary image with a background and a human body separated from each other; (2) transforming the distance of the binary image to obtain a geometric skeleton; (3) processing the geometric skeleton to find an end point and an inflection point as key points of the geometric skeleton; (4) marking the key points of the geometric skeleton with human joint semantics according to the relationship of the relative positions of human joints in a preset human skeleton model; (5) adopting a method integrating sparse features and optical flow tracking to find a corresponding matching point in a subsequent frame for each point which is successfully marked as a human joint; and (6) adopting a particle filtering method to estimate the possible state of the failure part in tracking results and recovering the tracking process.
