Image cropping and processing method for adjusting aspect ratio, electronic device, terminal device in communication with the electronic device, and non-transitory computer-readable recording medium

An electronic device of image cropping and processing for adjusting an aspect ratio, provided in communication with a database, the database receives an initial image and identifies a human being by artificial intelligence, is used to execute cropping to the initial image from a first aspect ratio to crop a cropped final image that meets a second aspect ratio, the electronic device comprises:

• a photography unit, for taking the initial image;
• and
• a processing unit, electrically connected to the photography unit, the processing unit comprises:
• a human body coverage area calculation module, for identifying coordinates of the human being in the initial image to define a human body coverage area, and defining a center point of the human body coverage area as a first focal coordinate;
• a cropping ratio calculation module, electrically connected to the human body coverage area calculation module, using the first focal coordinate as a center point to define a cropping frame, the cropping frame has the second aspect ratio, and the cropping frame corresponds to the human body coverage area and is enlarged according to a ratio parameter;
• a facial coverage area calculating module, for identifying coordinates of a face of the human being in the initial image to define a facial coverage area, and defining a second focal coordinate of a center point of the facial coverage area;
• and
• an alignment and cropping module, electrically connected to the cropping ratio calculation module and the facial coverage area calculation module, for defining a center point of the cropping frame as a third focal coordinate, moving the cropping frame to the third focal coordinate to coincide with the second focal coordinate, and when it is judged that the cropping frame is covered within the initial image, an image of the cropping frame is selected as the cropped final image.

A non-transitory computer-readable recording medium, storing a plurality of executable codes, after an electronic device reads the executable codes and executes, when there is a human being identified in an initial image by artificial intelligence, cropping to the initial image from a first aspect ratio is executed to crop a cropped final image that meets a second aspect ratio, comprising the following steps:

• calculating a human body coverage area:
• identifying coordinates of the human being in the initial image to define a human body coverage area, and defining a center point of the human body coverage area as a first focal coordinate;
• calculating a cropping ratio:
• using the first focal coordinate as a center point to define a cropping frame, the cropping frame has the second aspect ratio, and the cropping frame corresponds to the human body coverage area and is enlarged according to a ratio parameter;
• calculating a face coverage area:
• identifying coordinates of a face of the human being in the initial image to define a facial coverage area, and defining a second focal coordinate of a center point of the facial coverage area;
• and
• alignment and cropping:
• defining a center point of the cropping frame as a third focal coordinate, moving the center point of the cropping frame from the third focal coordinate to coincide with the second focal coordinate, and when it is judged that the cropping frame is covered within the initial image, an image of the cropping frame is selected as the cropped final image.
