Problems solved by technology

However, images that do not contain the intended expression may still have other significant effects (e.g. "sad" or "shocked" effects)
As a result, excellent images containing various other expressions besides the predetermined ones may be missed

Embodiment Construction

[0063] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the following description is merely explanatory and exemplary in nature and is in no way intended to limit the invention, its application or uses. Relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in the embodiments do not limit the scope of the present invention unless otherwise specifically stated. Additionally, techniques, methods and devices known to those skilled in the art may not be discussed in detail but are intended to be part of the description where appropriate.

[0064] As mentioned above, the image processing method of the prior art is based on the decision attribute value of the group, and the decision attribute value of the group is based on a plurality of predetermined attribute values ​​for all faces, thus the image processing method of the prior art has...

Abstract

The invention discloses an image processing device and an image processing method. The image processing device for an image sequence of a group comprises a unit configured to acquire the image sequence of the group, wherein the group includes at least two people; a unit configured to detect the face region of each person in each image in the image sequence; a unit configured to identify the attribute of the face region of each person in each image in the image sequence; and a unit configured to determine the attribute of the group on the basis of the attribute of the face region of each person in each image in the image sequence. The device and the method select the face region or image based on the attribute of the group so as to be capable of acquiring a satisfactory group image and / or dealing with various attributes except a predetermined attribute.

Description

technical field [0001] The present invention generally relates to the fields of image processing, computer vision and pattern recognition, and particularly relates to an image processing device for group image sequences and video sequences, and an image processing method for group image sequences and video sequences. Background technique [0002] Where a sequence of images is taken of a population (comprising at least two individuals, for example, comprising at least two people), it is often desirable to be able to easily obtain a satisfactory image therefrom, in which each person Attributes (for example, expression attributes such as "smile", "sadness" and "neutral", or motor unit attributes such as "wink", "wrinkle nose" and "open mouth") are satisfactory. [0003] To cope with this situation, various image processing methods have been proposed, one of which is shown in figure 1 (see US2011 / 0109770A1). exist figure 1 In the flowchart of , first, at step 10, each face in...
