Problems solved by technology

However, this method is only suitable for the recognition of simple scenes, such as the classification of indoor and outdoor, day and night, etc.
For scenes with a large number of scene categories or complex image backgrounds, the resolution ability is weak, which reduces the accuracy of scene recognition

Abstract

The invention provides a scene recognition method and device and an electronic device, and relates to the technical field of image processing, wherein the scene recognition method comprises the following steps of acquiring a scene feature map and a weight feature map of an image to be recognized; generating scene recognition information corresponding to the image to be recognized according to thescene feature map and the weight feature map; recognizing the scene recognition information by using a scene recognition model; and determining a scene category corresponding to the image to be recognized. According to the scene recognition method and device, and the electronic device provided by the embodiment of the present invention, the weight of the scene feature value of the scene feature map in the scene recognition information by acquiring different weight values of the scene feature values in the scene feature map of the image to be recognized, so as to improve the attention to key scene features, thereby improving the accuracy of complex scene recognition.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a scene recognition method, device and electronic equipment. Background technique [0002] Scene recognition is an important branch of image recognition technology, that is, a computer determines which scene a photo or image is in. Scene recognition helps to understand the high-level semantic information that a photo or image expresses. [0003] In current scene recognition systems on the market, traditional image recognition models are generally used. First, the global features of the image are extracted; then, based on the simple classification training results of a certain amount of data, the scene to which the image belongs is identified and classified according to the global features of the image. However, this method is only suitable for the recognition of simple scenes, such as the classification of indoor and outdoor, day and night scenes. However, for...
