一种图像识别方法及装置

Method and device for identifying image

Abstract

The invention provides a method and device for identifying an image. The method and device solve the problems that in an existing image identification process, more resources are consumed, the efficiency is quite low, and the time cost is quite large. The method comprises the steps of establishing a first voting image for one image of each category, being capable of obtaining k comparison characteristics matched with practical characteristics, and obtaining the categories of the comparison characteristics and the relative central positions of the comparison characteristics, so that the various categories are obtained through one-time matching. Subsequently, the similarity can be calculated for the comparison characteristics of each category, the estimated central positions of the comparison characteristics in the first voting images are determined, then the similarities can be increased at the estimated central positions, and finally the first voting images of the various categories can be obtained. Then, the first voting image, corresponding to the estimated central position, with the maximum similarity is obtained, and the category of the corresponding first voting image is the category of the image to be detected.
本申请提供了一种图像识别方法及装置,以解决现有图像识别的识别过程会消耗比较多的资源,并且效率非常低,时间开销非常大的问题。本申请针对每一类别的图像建立一张第一投票图像,可以获取与所述实际特征匹配的k个对比特征,并获取所述对比特征的类别和对比特征的相对中心位置,因此,本申请通过一次匹配就可以获取到多种类别。后续针对每个类别的对比特征,可以计算相似度,并确定所述对比特征在第一投票图像中的估计中心位置,然后可以在所述估计中心位置处增加所述相似度,最终可以获取到多个类别的第一投票图像。然后获取相似度最大的估计中心位置对应的第一投票图像,所述第一投票图像的类别即为待检测图像的类别。
