Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] The main idea of ​​the present invention is to use three image processing strategies to generate thumbnails at the same time, so that important image content can be accurately, completely and fully displayed in the thumbnails, so that the thumbnails can maximize the retention of important information of the original image and improve Improve user browsing efficiency and browsing experience while reducing algorithm complexity.

[0029] Below at first the term that the present invention relates to is explained:

[0030] Crop: The image content inside the crop window is preserved, while the area outside the crop window is discarded. The clipping strategy in the present invention will give priority to retaining the im...

Abstract

The invention discloses a thumbnail generation method and system. By combining the three image processing strategies of cropping, distortion and zooming to generate a thumbnail, advantages of the different strategies are exerted, the different strategies are supplemented by each other, an important region in an image is accurately, completely and fully displayed in the thumbnail, and important information is preserved to the maximum in the limited space of the thumbnail. According to the thumbnail generation method and system, the three image processing strategies are achieved through one uniform optimization process, and therefore the time overhead is small.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and system for generating image thumbnails. Background technique [0002] In recent years, with the continuous development of multimedia and Internet technologies, visual data such as images and videos have exploded. In order to quickly browse images, mobile phones, IPads, computers and other devices first convert images into small-sized thumbnails, and then display thumbnails of multiple images on the screen at the same time to facilitate users' browsing. [0003] According to the survey, currently the thumbnail generation methods adopted by almost all devices are cropping or uniform scaling. Cropping is to directly capture a target size area in the middle of the original image as a thumbnail, while uniform scaling is to compress the original image to the size of the thumbnail at a fixed ratio. However, uniform scaling often results in severe deformation of important o...
