Abstract

The embodiment of the invention provides a video image cutting method and device, electronic equipment and a storage medium. The method comprises the following steps: determining the position of a target object for a selected target video image; wherein the target object is an object to be contained in the cut target video image; determining the range of a to-be-cut area in the currently selectedtarget video image according to the position of the target object; determining edge pixel point coordinates of the to-be-cut area according to the range of the to-be-cut area; and cutting the to-be-cut area according to the edge pixel point coordinates of the to-be-cut area to obtain a cut video image. According to the video image cutting method and device, the electronic equipment and the storagemedium provided by the embodiment of the invention, the range of the to-be-cut area is determined by identifying the target object in the target video image, so that the target object is located at arelatively fixed position in the video image obtained after cutting; and the blank condition of the cut video image is avoided.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video image clipping method, device, electronic equipment and storage medium. Background technique [0002] When processing an image, it is usually necessary to adjust the size of the image, such as enlarging the image, reducing the image, cropping the image, and the like. [0003] When cropping an image, pixel loss occurs, resulting in a reduced resolution of the cropped image. [0004] Those skilled in the art have proposed a bilinear interpolation algorithm and a Lanzcos interpolation algorithm for the problems encountered in image cropping. The bilinear interpolation algorithm can crop the image according to the specified pixel coordinates, and the Lanzcos interpolation algorithm can perform pixel compensation on the static image. Combining bilinear interpolation algorithm and Lanzcos interpolation algorithm, it can change the size of single frame image while maint...
