Embodiment Construction

[0027] In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The following descriptions are only some embodiments of the present invention. For those of ordinary skill in the art, Other implementations of the present invention can also be obtained according to these embodiments without paying creative efforts.

[0028] Please refer to figure 1 , which shows a flowchart of a method for tracking multiple objects according to a preferred embodiment of the present invention. This method is suitable for image processing, and the generation time of the plurality of second image data (t-1 second) is before the first image data (t second). The method includes the following steps: the method inputs first image data S102. Then, the method executes an object cutting step to obtain a foreground object as an object S1...

Abstract

The invention discloses a method for tracing multiple objects, in particular to an image processing method which is suitable for image processing and comprises the following steps: performing a model establishing program so that each pixel of second image data and first image data individually has a color parameter and a position parameter, then a first object of the first image data is individually disassembled into a plurality of first sub-blocks, then a second object of the second image data is individually disassembled into a plurality of second sub-blocks, and then an article block is formed according to the first sub-block and the second sub-block.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for tracking multiple objects according to five-dimensional parameters. Background technique [0002] The intelligent video surveillance system can identify moving objects from images, track objects, and then judge events that have occurred. The existing automatic object tracking method is to establish the corresponding relationship of objects on the time axis, so as to obtain the moving track of the object, and then perform event detection. In addition, existing automatic object tracking methods use object features, such as: object image, object appearance model (Appearance Model), color, bounding box (Bounding Box), etc., to establish object correspondence. That is to say, the existing automatic object tracking method is based on video segmentation and connected component analysis. Existing methods for automatic object tracking then obtain features of the connected compo...
