Embodiment Construction

[0030] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0031] The present invention proposes a target tracking method based on color distance and image segmentation and aggregation, and proposes a new calculation method closer to the actual color model in the calculation of histogram distance (similarity), which can better describe The difference between the two colors makes the matching result more accurate. For the detection method of moving objects, the method of image segmentat...

Abstract

The invention relates to a target tracking method based on color distance of multicolors and image dividing and aggregating. The target tracking method based on the color distance of multicolors and the image branch and aggregation includes the following steps: a rectangular target is selected, an outline of a pretracking target is generated, color histogram framework is calculated, an area of a next image is divided and aggregated to obtain a divided area, and the divided area is matched up with the color histogram framework to achieve target tracking. By means of the target tracking method based on the color distance of multicolors and the image dividing and aggregating, the situations that the tracking algorithm has an excessive demand on environment and the tracking is inaccurate are avoided.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a target tracking method based on color distance and image classification aggregation. Background technique [0002] Object tracking is a very important research direction in the field of computer vision, and it is also one of the core technologies in the field of intelligent video surveillance. The existing target tracking algorithm will be affected by many environmental aspects (illumination changes, shape changes, etc.) in operation, and it is difficult to meet the robustness requirements in complex environments in the field of intelligent video surveillance. This invention provides a solution for this problem feasible solution. [0003] The traditional particle filter tracking algorithm based on color histogram includes the following steps: [0004] Step 1. Select the target and calculate the color histogram template of the pre-tracking target. [0005] Step...
