Problems solved by technology

However, the difference between the evaluated target and the training sample should not be too significant, and if it is necessary to modify the classifier parameters with different samples, the calculation is very complicated, which is not conducive to dealing with the situation where the sample changes are not clear

Embodiment Construction

[0042] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0043] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

The invention discloses a target distinguishing method and a target distinguishing device. The target distinguishing method of the invention comprises: a characteristic extraction step: extracting the characteristic of each target in a target area; a target difference calculation step: calculating the difference between the current characteristic of each target to be distinguished and the characteristic of each target in the target area, which is extracted in the characteristic extraction step; a difference distinguishing step: taking the difference between the current characteristic of each target to be distinguished, which is calculated by the target difference calculation step and the characteristic of each target in the target area as a new characteristic of each target to be distinguished, and calculating the difference among the new characteristic of each target to be distinguished so as to partition each target to be distinguished.

Description

technical field [0001] The present invention generally relates to pattern recognition, and in particular to an object distinguishing method and object distinguishing device, which are used to accurately distinguish each object when the number of objects is greater than or equal to two in pattern recognition. More specifically, the present invention relates to target similarity calculation, especially to a method and device for calculating the similarity between a target in a target area and a target of interest in image or video data, and accurately distinguishing the target. Background technique [0002] In pattern recognition, judging the similarity of multiple objects is the premise of all work. The existing judging methods are divided into two categories, one is based on difference measurement theory, and the other is based on learning theory. [0003] The method based on the difference measurement theory uses different distance measurement criteria to directly compare ...
