Abstract

The invention provides an image cutting method and device, a terminal and a readable storage medium. The cutting method comprises the following steps: carrying out binarization processing on a to-be-cut image to obtain a binary image; and obtaining an effective area mask image and a frame mask image according to the binary image. And obtaining the maximum inscribed frame of the to-be-cut image according to the effective area mask pattern and the frame mask pattern. And cutting the to-be-cut image according to the maximum inscribed frame to obtain a target image. According to the clipping method and device, the terminal and the readable storage medium, the effective area mask image and the frame mask image are obtained according to the binary image, the maximum inscribed frame of the to-be-clipped image can be obtained by combining the effective area mask image and the frame mask image, and the to-be-clipped image is clipped by using the maximum inscribed frame, so that the clipping efficiency is improved. Compared with a manual cutting mode, the cutting efficiency is greatly improved, the target image can contain an effective area as large as possible in the to-be-cut image, and the cutting effect is better.

Description

technical field [0001] The present application relates to the field of imaging technologies, and more particularly, to an image cropping method, an image cropping device, a terminal, and a non-volatile computer-readable storage medium. Background technique [0002] Image stitching is a technique of stitching multiple overlapping images of the same scene into a larger image, which is of great value in photography, image editing, medical imaging, remote sensing and other fields. However, in the process of image stitching, it is necessary to perform perspective transformation on the images to be stitched, which will inevitably lead to the existence of black invalid areas around the stitching result. The result is cropped so that a satisfactory result is obtained. However, most of the cropping of the stitching results is done manually, which has low cropping efficiency. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide an image cropping method,...
