Embodiment 1

[0064] like figure 1 As shown, the present invention provides a method for identifying a subject type, the method comprising:

[0065] Based on the shooting information, it is judged whether the shooting mode in the shooting information is a portrait, and if so, the first judgment item v 1 (P)=1, otherwise, let v 1 (P) = 0;

[0066] Based on the shooting information, it is judged whether the shooting location is a popular shooting area, and if so, the second judgment item v 2 (P)=0, otherwise, let v 2 (P)=1;

[0067] Determine whether the number of face regions is greater than 0,

[0068] If so, determine whether the proportion of the portrait area is greater than the first proportion threshold, and if so, make the third judgment item v 3 (P)=1, otherwise, let v 3 (P) = 0;

[0069] If not, determine whether the shooting location is a popular shooting area, and if so, identify the subject type as the background.

[0070] Calculate whether the judgment value V(P) is gre...

Embodiment 2

[0095] The present invention also provides a subject type identification system, a subject type identification system, the system includes a memory, a processor, and a computer program stored in the memory and operable on the processor, the processor executes The computer program realizes the following steps:

[0096] Based on the shooting information, determine whether the shooting mode in the shooting information is a portrait, if so, set the first determination item v1(P)=1, otherwise, set v1(P)=0;

[0097] Based on the shooting information, determine whether the shooting location is a popular shooting area, if so, make the second judgment item v2(P)=0, otherwise, make v2(P)=1;

[0098] Determine whether the number of facial regions is greater than 0, if so, determine whether the proportion of the portrait area is greater than the first proportion threshold, if so, set the third determination item v3(P)=1, otherwise, set v3(P)=0;

[0099] Calculate whether the judgment val...

Abstract

The invention provides a shooting subject type identification method and system, and relates to the technical field of image identification. According to the method, the image is analyzed from the three dimensions of the shooting mode, the shooting position and the portrait area proportion, the shooting subject type of the image is recognized, the shooting subject type is divided into the figure type, the background type, as well as the figure and background type, the shooting subject type of the image is recognized on the whole, and support is provided for subsequent preview generation.

Description

technical field [0001] The invention relates to the technical field of cloud mobile phones, in particular to a method and system for identifying the type of a shooting subject. Background technique [0002] When generating a preview image of an image, it is often necessary to first determine the type of subject in the image, and then select different scaling strategies for different types of subjects, and finally generate a preview image. [0003] However, the existing methods for identifying the subject type usually use the central area of ​​the image as the position of the subject type, and then identify the object at the position of the subject to determine the subject type. [0004] However, in actual shooting, the composition of the shot is often not to set the subject at the center. The above method only considers the objects in the local area, and cannot identify the type of the subject from the image as a whole, and it is easy to miss information in other areas. The...
