Problems solved by technology

In this way, if you want to find a picture of a human face from some pictures at some time, or find a specific human face, you can use such a small thumbnail Figure 1 It is generally difficult to see the faces clearly, so you have to open the picture files one by one to find
For example, after a family returns from a trip, it usually takes a lot of time and energy for the user to find all the photos of the youngest daughter.
Moreover, this method also takes up a lot of system resources when decoding larger entire image data

Embodiment Construction

[0011] Hereinafter, the present invention will be described in detail.

[0012] refer to figure 2 , which shows a face detection-based image preservation method of the present invention.

[0013] First input the image (101), utilize the face detection module to carry out face detection (102) to the whole image, judge whether to detect a face (103), if a face is detected, then use the face area as a reference map (104) , otherwise, take the entire image frame as the reference map (105). Next, the reference image is scaled to the thumbnail size (106), that is, a thumbnail with a predetermined size is obtained. Finally, the thumbnail image and the entire input image are combined into an image file for saving (110).

[0014] Preferably, before merging and saving, the thumbnail can also be compressed and encoded (107) to obtain the code stream data of the thumbnail, and the image compression module is also used to compress and encode the input image (108) to obtain The code st...

Abstract

The invention relates to an image storage method based on face detection, comprising: inputing an image; processing the face detection for the image, wherein, if the face is detected, making face region as a reference image, or making the image as the reference image; scaling the reference image to gain a thumbnail with expected size; and combining the image and the thumbnail and saving. The method of the invention can easily find out related picture according to the face in the thumbnail when using thumbnail model to quick browse a plurality of pictures.

Description

technical field [0001] The invention relates to an image preservation method, in particular to an image preservation method based on face detection. Background technique [0002] Thumbnail refers to reducing the original image in proportion as a preview of the original image. This is a more intuitive way to display files. In this display mode, the thumbnail content of images, text type files, etc. will replace the files. icon, so that you can quickly view the content of the picture without opening the file, which is very convenient. [0003] Some image formats can support thumbnails, such as JPEG image format. The size of the thumbnail is very small, generally around tens of pixels, so it accounts for a very small proportion of the entire file size. A lot of software supports the thumbnail browsing mode, for example, the file browser (Explorer.exe) that comes with Microsoft’s windows XP system, such as figure 1 As shown, by selecting the "Thumbnail" option, you can browse...
