Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] figure 1 A schematic diagram of an apparatus for determining image sharpness according to one aspect of the present invention is shown. Wherein, the determining device 1 includes, but is not limited to, a network host, a single network server, a set of multiple network servers, or a cloud formed by multiple servers. Here, the cloud may be constituted by a large number of computers or network servers based on cloud computing (Cloud Computing), wherein cloud computing is a kind of distributed computing consisting of a group of loosely coupled computer sets consisting of a super virtual computer. Wherein, the determining device 1 includes a first obtaining means 11 , a second obtaining means 12 and a first determining means 13 .

[0023] The first acquiring device 11 acquires an image whose image definition is to be determined. Specifically, the first ...

Abstract

The present invention provides a device and method for determining image clarity, comprising: acquiring an image to be determined image clarity; according to the image, acquiring low-frequency noise corresponding to the image; based on the SVM definition classifier, Based on the low frequency noise, image sharpness of the image is determined. Compared with the prior art, the present invention does not need to preset any reference model when sorting the image query results, by obtaining the image clarity of the image query results, and reordering the image query results based on the image clarity Clear images and blurred images in the results to improve the user's image search experience.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an image processing technology for determining image clarity. Background technique [0002] In applications such as search engines or image retrieval systems, an image query sequence is likely to correspond to multiple image query results, and the order of these image query results often depends on various factors. In the prior art, in order to determine the order in which the image query results are provided, most of the time the image query results must be evaluated using a preset reference model, and then the image query results are sorted based on the evaluation results. However, the above-mentioned preset reference models for evaluation need complex data processing to obtain, and different image query results may apply different reference models, which will also result in a large number of reference models and low compatibility. [0003] In view of this, how to design ...
