Problems solved by technology
[0002] With the rapid development of the multimedia era, as well as the convenience and diversification of taking pictures, users have more and more demands on image editing in various aspects, such as cropping images on the Internet, editing magazines or editing new media resources. A large number of images need to be cropped, or ordinary users need to process a large number of images that are usually taken by themselves. The cropping process requires high labor costs, a lot of repetitive work, and low processing efficiency.
[0003] If the image can be automatically cropped, it will save a lot of labor cost and time cost, but the image cropped by the existing automatic image cropping technology is not satisfactory, and it is prone to incomplete cropping, loss of the main image, or cropped image. The problem that the main image of the image is rendered in an inappropriate position

Embodiment Construction
[0025] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.
[0026] The computer equipment includes user equipment and network equipment. Wherein, the user equipment includes but is not limited to a computer, a smart phone, a PDA, and the like.
[0027] It should be noted that the user equipment, network equipment, and network are only examples, and other existing or future computer equipment or networks that are applic...

The invention provides an image cropping method and an image cropping apparatus. The method comprises the steps of identifying a main body image of a to-be-cropped image and marking a profile corresponding to the main body image; according to the profile of the main body image of the to-be-cropped image, determining a circumscribed rectangle and a center position point corresponding to the main body image; under the condition that the circumscribed rectangle does not exceed a range of a cropped rectangle corresponding to an image cropping demand and the cropped rectangle does not exceed a range of the to-be-cropped image, determining the position of the cropped rectangle as a cropping position of the to-be-cropped image when a distance between a prime position point of the cropped rectangle and the center position point is minimal; and according to the cropping position, cropping the to-be-cropped image. The main body image in the to-be-cropped image can be ensured not to be lost; thepresented position of the main body image in the cropped image is more reasonable; and a large amount of manpower and time costs are reduced.
Description
technical field [0001] The invention relates to the field of image processing, in particular to an image cropping technology.
