The present disclosure relates to methods and systems for data visualization. The systems may perform the methods to obtain a video having a plurality of frames including a plurality of objects; identify a target object from the plurality of objects according to the plurality of frames; determine one or more track points of the target object, each of the one or more track points being corresponding to the target object in one of the plurality of frames; determine a first track of the target object based on the track points, the first track including at least one of the one or more track points of the target object; determine a second track of the target object based on the first track, the second track including at least one of the track points of the first track; generate a video analysis result by analyzing the second track; and visualize the video analysis result.

Methods and systems for data visualization

A method for generating a video synopsis may include: segmenting a video file into a plurality of video fragments. The method may also include extracting moving object information from the video fragment based on a distributed computing method and determining a plurality of index files based on the moving object information. The method may further include combining the plurality of index files and generating a video synopsis based on the moving object information and the combined index file.
