Abstract

The present disclosure relates to a scene recognition method and device, wherein the scene recognition method includes an acquisition step of acquiring feature values ​​of a frame image to be recognized, the frame image to be recognized includes a current frame image and a previous frame image, and the previous frame image is the current frame The first Nth frame image of the image; the judging step, according to the comparison feature value similarity and threshold, judge whether to perform the scene recognition step, wherein the feature value similarity is between the feature value of the current frame image and the feature value of the previous frame image Similarity; the scene recognition step includes performing scene recognition based on the current frame image. Through a scene recognition method of the present disclosure, the times of scene recognition can be reduced, thereby effectively reducing power consumption.

Description

technical field [0001] The present disclosure relates to the technical field of scene recognition, in particular to a scene recognition method and device. Background technique [0002] For some devices with image acquisition functions, such as mobile phones with shooting functions, they often use scene recognition technology to classify the real-time preview scenes after turning on the camera and starting the camera preview, and classify the results according to different scenes. Different image exposure and processing methods are adopted to present users with a preview effect that is closer to the perception of the human eye, and to take photos that look more realistic to the human eye. During the camera preview process, since the camera performs scene recognition and result output for each frame of captured image data, the power consumption of the device is increased. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the pre...
