Abstract

The invention discloses an image down-sampling method, electronic equipment and a storage medium. The method comprises the following steps: acquiring original size information of an original image; acquiring a sliding window corresponding to the original image based on the original size information and the target size information; dividing the region of the original image into a plurality of sub-regions by using a sliding window; and performing down-sampling processing on each sub-region to obtain a target image. In this way, the applicability of the image down-sampling method can be improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to an image down-sampling method, electronic equipment and a storage medium. Background technique [0002] At present, image processing methods are widely used, for example, image processing technology is applied in transportation, monitoring, industry, medical treatment and other fields. Generally speaking, it is necessary to pre-process the image before processing the image, or to perform post-processing on the image after processing the image, that is, to perform size conversion on the image. [0003] Wherein, image size transformation may be performed by image downsampling. Image down-sampling may also be called image down-sampling. Image down-sampling mainly reduces the size of an image and generates a thumbnail of the corresponding image, so that the generated image conforms to the corresponding display area. However, the existing image downsampling methods are not ...
