Description

Group photo method and device

technical field

The invention relates to the field of digital publishing, in particular to a method and device for group photos.

Background technique

At present, in the field of newspaper production, group photos are often used to provide news pictures and news reports. A group photo is a group of images used to describe a photographic subject. For example, during the two sessions, several pictures of the leader's speech can form a group photo. When the editor of the newspaper office reports on the two sessions, he can quickly and effectively find the photos of the leader through the group photo sketch and group photo description, and select one of these photos. Use one or more sheets.

The process of grouping photos is generally completed by the reporter who takes the pictures. In the prior art, the process of generating group photos is as follows:

1. The reporter takes several pictures with the camera;

2. The reporter exports the pictures in the camera to the application system;

3. The reporter browses these pictures and artificially judges which pictures should belong to the same group of pictures;

4. The reporter adds a description file to the same group of pictures to form a group photo.

The above method requires reporters to manually judge which pictures can constitute a group photo, and manually carry out the operation of group photos. There are shortcomings such as low timeliness for reporters to provide news pictures, complicated manual operation, and inability to report emergency news in a timely manner. .

Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings and examples.

Aiming at the problems of complex operation, low efficiency, and poor timeliness caused by manual group photo operation in the prior art, the embodiment of the present invention provides a group photo method and device, which can automatically realize group photo, so as to solve the above problems.

As shown in Figure 1, it is a flow chart of the group photo method in the embodiment of the present invention, including the following steps:

Step 101, acquire new pictures from the memory card of the digital camera.

Specifically, the smart SD card of the digital camera can be scanned by the mobile phone to obtain new pictures from the SD card.

Step 102, determine whether the new picture and the existing picture are consecutive pictures.

When determining whether two pictures are continuous pictures, it can be determined according to the shooting time of the two pictures. If the time interval between the two pictures is within the set time threshold (such as 3-5 minutes), it is determined as a continuous picture . Otherwise, it is a discontinuous picture.

Step 103, if yes, extract pixel information of the new picture and the existing picture respectively.

In the embodiment of the present invention, for two consecutive pictures, it is further necessary to judge whether they are similar pictures according to the pixel information of each picture, so as to ensure the accuracy of the judgment. Specifically, pixel points at the four corners and central points of the new picture and the existing picture may be extracted respectively, and RGB values of the pixel points may be obtained.

Step 104: Determine whether the new picture is an approximate picture of the existing picture according to the pixel information.

If the RGB values of corresponding pixels in the new picture and the existing picture are both smaller than a set similarity threshold (for example, less than or equal to 3), then the new picture is an approximate picture of the existing picture.

It should be noted that it is necessary to compare the extracted pixels at each position one by one,

Step 105, if yes, form a group photo with the new picture and the existing picture.

It should be noted that, in practical applications, the above-mentioned existing pictures may be existing pictures within a certain range of the shooting time of the new picture, for example, pictures whose time interval is within 3-5 minutes, and Images already in the phone outside of this time frame will not be compared. Moreover, when comparing, it is necessary to compare the new picture with the existing pictures one by one. If the picture to be compared is already in a group photo, add the new picture to the group photo; pictures to form a new group photo.

It can be seen that by using the group photo method provided by the embodiment of the present invention, the group photo can be automatically realized, especially in the field of newspaper production, which can greatly simplify the process of reporters group photo and improve efficiency.

It should be noted that the group photo method provided by the embodiment of the present invention can be applied to various terminal devices, such as mobile phones and IPADs.

Further, in the embodiment of the present invention, the above-mentioned terminal device may also transmit the generated group photo to the publishing platform through a communication network (such as the Internet, a wireless network, etc.).

The group photo and its description information are transmitted to the release platform through the communication network, so that other relevant personnel can directly view and use it through the release platform, eliminating many intermittent actions that were originally done manually.

Further, in order to better distinguish each group photo, the terminal device may also generate description information of the group photo, and transmit the description information together with the group photo to the publishing platform.

The descriptive information for generating group photos may specifically include the following aspects:

Generate group photo ID;

Extract group photo title, group photo description and other information. Specifically, it can be extracted from the IPTC (International Press Telecommunications Council, International Press Telecommunications Council) metadata of the image. IPTC metadata is a standard format, and the following metadata can be added to photo information, such as author, copyright, subtitle, detailed description, etc.

Establish the association relationship between group photos and pictures.

For example, you can preset the description of the group photo, for example, preset "Two Sessions Topic", then the default description of the first group of pictures is "Two Sessions Topic Group Photo 1", and the second group of picture description is "Two Sessions Topic Group Photo 2"...

It can be seen that by using the method for group photos in the embodiment of the present invention, many intermittent actions that were originally done manually can be avoided, and the rapid transfer of pictures by reporters is realized, which improves the work efficiency in the process of news reporting.

The effect of the invention is that the high-definition pictures of the professional camera are quickly transmitted to the newspaper office through the wireless network of the mobile phone, which not only ensures the quality of the pictures, but also improves the speed of transmitting the pictures. Using the method of rapid photo transfer by reporters improves the efficiency of reporters returning news pictures taken by professional cameras to the newspaper office, saving the time for reporters to go back and forth to the newspaper office, and using the high coverage and high availability of the mobile phone wireless network to ensure that in extremely harsh conditions Under certain conditions, the pictures can also be returned to the newspaper.
