Problems solved by technology

Because different users have different aesthetic feelings for the same image, and the same user often has their own stable aesthetic preferences in the selection of multiple recommended images.

Embodiment Construction

[0022] Such as figure 1 As shown, a multi-dimensionally driven intelligent camera method based on user preference includes the following specific steps:

[0023] Step 1, the initial positioning of the photo scene, using the pre-trained lightweight network to identify the category of the photo scene, specifically:

[0024] S101, cache the preview image in the camera and denote it as I q , using the trained convolutional neural network for outdoor scene recognition (shooting scenes are divided into K categories);

[0025] S102, the scene category is matched with the scene category that exists in the pre-trained network, if the preview image is in the kth category scene, i.e. q ∈k (k=1,2,...K), then go to step 2; otherwise, shoot directly without performing subsequent steps.

[0026] Step 2, extract the feature vectors of the preview image and the professional portrait photos in the scene, and match them according to the similarity, and select the most similar pictures, specif...

Abstract

The invention provides an intelligent photographing method based on user preference multi-dimensional driving, and the method comprises the steps: firstly obtaining a preview picture of a camera, andanalyzing a scene to which the preview picture belongs; if the scene exists in the scene database, continuing to inquire the professional portrait scenery picture data set under the scene category; and performing a matching operation according to the picture scene similarity to find a group of pictures with the highest background similarity; finally, calculating a picture most likely to be liked by the user through the user preference learning model, and taking the picture as a final shooting reference picture to guide the shot person to lay down the posture, thereby improving the shooting experience of ordinary people.

Description

technical field [0001] The invention belongs to the field of computer photography and image processing, and relates to an intelligent photographing method based on multi-dimensional drive of user preference. Background technique [0002] With the rapid development of various mobile smart devices, mobile devices (tablets and smart phones) have become an indispensable tool in our daily life. In addition, the pixels of mobile cameras are getting higher and higher, and digital cameras are relatively bulky and expensive, so most users prefer to use mobile phones to take pictures instead of digital cameras. [0003] However, taking high-quality photos requires users to have certain photographic composition skills. Obviously, most users don't have compositional skills. Although some people have proposed composition methods for portrait shooting, most of them simply analyze the position of the human body in the image, and use composition rules such as the rule of thirds to guide t...
