Embodiment Construction
[0040] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0041] In the image cutting method provided by the embodiment of the present invention, after the image is recognized to obtain local feature information, the complete face information is obtained through the local feature information, and the position of the face information in the image is positioned, and then the facial information is ensured. Under the premise of the integrity of the information, the cutting area of the image is determined according to the size of the image.
[0042] figure 1 It is a flow chart of the image cutting method provided by the embodiment of the present invention. As shown in the figure, the method includes:
[0043] S101: Obtain image information.
[0044] After the image to be cut is determined, a data packet of the image is obtained, and the data packet includes all image informati...

An embodiment of the present invention relates to an image cutting method. The method comprises: obtaining image information; identifying the image information to find local feature information of a human face; and performing face recognition according to the local feature information of the human face so as to obtain face information; finding location coordinates (x, y), and (x+w, y+h) of the face information in the image information; calculating location coordinates (x+w / 2, y+h / 2) of a face center point in the face information; calculating a point at which the face center point is closest to the edge location in the image information; and taking a distance between the nearest point and the face center point as a first cutting distance and performing a rectangle cutting with the face center point as a first center point so as to obtain a first cutting image. According to the image cutting method provided by the embodiment of the present invention, the location of a human face in an actor picture can be determined, a more accurate picture of an actor can be obtained, and a complete display of a human face can be ensured.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to an image cutting method. Background technique [0002] When introducing movies and programs, some mainstream video software currently displays the avatar in a circle, which makes the terminal interface display more abundant. But since the original picture is usually rectangular, it will be cut into a circle when displaying the avatar. During the interception, because the pictures of the actors are different and the positions of the faces are not uniform, ordinary interception methods often cause some pictures of the actors to fail to fully display the faces. Contents of the invention [0003] The purpose of the present invention is to provide an image cutting method that can more accurately intercept the actor's picture and ensure the complete display of the human face by judging the position of the human face in the actor's picture. [0004] To achieve the above object, th...
