Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0040] The embodiment of the present application discloses an image classification scheme, which adopts a multi-level classification model for image classification. First, the structure of the multi-level classification model is introduced, specifically: the multi-level classification model is a classification model sequence composed of at least two-level classification models arranged in sequence from low-level to high-level, and the output of the previous level classification model...

Abstract

The invention discloses an image classification method and a device. The method comprises the following steps: obtaining an image set to be classified; A set of images to be classified is inputted into a classification model sequence for classification, The classification model sequence includes at least two classification models arranged in order from a lower level to a higher level, wherein theset of images to be classified is input to a first classification model in the classification model sequence, and a non-noisy image to be classified output from the lower classification model is usedas an input of an adjacent higher classification model; A classification result of the image to be classified by the highest-level classification model in the classification model sequence is outputted. In the present application, classification accuracy is ensured while classification speed is improved in the above manner.

Description

technical field [0001] The present application relates to the field of image processing, and more specifically, to an image classification method and device. Background technique [0002] The image classification method is a method of using a computer to identify the category of an image or a certain object in an image. [0003] At present, a single image classification model is generally used for image classification, and in order to ensure the accuracy of image classification, an image classification model with a complex structure is required. However, although a single image classification model with a complex structure can improve the accuracy of image classification, its processing capacity is limited and cannot meet the real-time requirements of massive image data classification. Contents of the invention [0004] In view of this, the present application provides an image classification method and device, which are used to solve the problem that although a single im...
