Abstract

The invention discloses an intelligent picture cutting method and system, computer equipment and a storage medium. The method comprises the following steps: firstly detecting whether a human face exists in a picture or not, further verifying the validity, verification number, size and position of a target if the human face exists in the picture, and discarding the picture if the human face is toosmall or at the edge of the picture; if the effective human face exists, calculating a key feature region range based on the human face information; if no effective face exists, whether a body existsor not is detected, If the body is detected, the effectiveness of the target is further detected; if the effective body exists, calculating a key feature region of the picture based on the body information; if the effective body is not detected, significance detection is carried out on the picture, then a key feature area in the picture is calculated, and finally the picture is cut according to the key feature area and the required size. The method has the technical advantages of being high in cutting speed, accurate, intelligent, flexible to use and the like.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a picture intelligent cropping method, system, computer equipment and storage medium. Background technique [0002] The simplest methods of image cropping are scaling and center cropping. But they have obvious limitations. When the aspect ratios of the input and output images differ too much, scaling can severely distort the image. At the same time, if the image is reduced too much, some original user-sensitive information in the image, such as the text in the image, will not be recognized (cropping, compression and retrieval of massive images [M], 2013). In the early days, some scholars proposed seam carving for content-aware image resizing [J], Improved seam carving for video retargeting. [J]), this technology can well ensure that the important objects in the original image are not damaged. Under the premise of modifying the size of the original image, i...
